Add initial support for the MakerLisp eZ80 board. Ref: https://makerlisp.com/

Squashed commit of the following:

    configs/makerlisp:  Update comments about use of serial console.

    configs/makerlisp:  Add LED support, remove vestiges of button support (the board has no user buttons).  Add support for SPI-based MMC/SD card slot.

    arch/z80/src/ez80:  Fix some link problems.

    libs/libc/syslog/lib_syslog.c:  The ZDS-II toolchain does not declare va_coy in stdarg.h.  I think that the use of va_copy in vsyslog() is no necessary.

    configs/makerlisp:  Initial configuration directories cloned from ez80f910200zco with little more than naming changes.

+==========
+
+The MakerLisp machine is a portable, modular computer system, designed to
+recapture the feel of classic computing, with modern hardware.
+
+The machine centers on a 2" x 3.5" business card-sized CPU, which can be used
+stand-alone, or plugged in to a 2" x 8" main board, for expansion into a full
+computer system.  A laser-cut wood enclosure holds a small keyboard, an LCD
+monitor, the circuit boards, and a prototyping area with a breadboard for
+electronics experimentation and development.
+
+The CPU is a Zilog eZ80 running at 50 MHz, with up to 16 Mb of zero-wait state
+RAM. A VGA display adapter provides an IBM PC-like color text-mode display. A
+USB Host Controller supports a USB keyboard and other USB communications.
+Data storage and interchange is accomplished by a micro-SD card supporting the
+FAT file system. All four of these circuit boards (shown on the web site's cover
+page) are new MakerLisp products, and will be available as part of the first
+product offering

+ZDS-II Compiler Versions
+========================
+
+Version 5.3.0
+
+  The initial bring-up of the MakerLisp board used the ZiLOG ZDS-II 5.3.0
+  toolchain.  To use this toolchain, I had to suppress the gmtime() and
+  gmtimer() because these were causing an internal compiler error:
+
+    time\lib_gmtimer.c
+    P2: Internal Error(0xB47E59):
+            Please contact Technical Support
+
+  This is the change to suppress building these files:

+
+Serial Console
+==============
+
+  There are two options for a serial console:  (1) A UART connected to a
+  terminal program or (2) the MakerLisp Serial Keyboard and VGA display.
+
+UARTs
+-----
+
+  The eZ80 has two UART peripherals:
+
+  UART 0:  All of Port D pins can support UART0 functions when configured
+  for the alternate function 7.  For typical configurations only RXD and TXD
+  need be configured.
+
+    eZ80 PIN        BOARD SIGNAL CN1 ACCESS
+    =======================================
+    PD0/TXD1/IR_IXD CN1_TX0      Pin 61
+    PD1/RXD1/IR_RXD CN1_RX0      Pin 59
+    PD2/RTS1        CN1_RTS0     Pin 63
+    PD3/CTS1        CN1_CTS0     Pin 65
+    PD4/DTR1        CN1_DTR0     Pin 67
+    PD5/DSR1        CN1_DSR0     Pin 69
+    PD6/DCD1        CN1_DCD0     Pin 71
+    PD7/RIO1        CN1_RI0      Pin 73
+
+  UART 0:  All of Port C pins can support UART1 functions when configured
+  for the alternate function 7.  For typical configurations only RXD and TXD
+  need be configured.
+
+    eZ80 PIN        BOARD SIGNAL CN1 ACCESS
+    =======================================
+    PC0/TXD1        CN1_TX1      Pin 62
+    PC1/RXD1        CN1_RX1      Pin 60
+    PC2/RTS1        CN1_RTS1     Pin 64

+    PC6/DCD1        CN1_DCD1     Pin 72
+    PC7/RIO1        CN1_RI1      Pin 74
+
+Serial Keyboard and VGA Display
+-------------------------------
+
+  The serial console can also be implemented using the MakerLisp USB
+  Keyboard Controller Board and VGA Display Controller.  These are accessed
+  via the two UART ports.
+
+  [more to be provided]
+
+LEDs and Buttons
+================
+
+LEDs
+----
+
+  Three LEDs are available on the CPU Card, but none are available for
+  general use by applications:
+
+  D2 RED:    CPU Card power.  Not under eZ80 control
+  D3 GREEN:  Driven by CPU GPI/O pin.  However, it has some additional
+             properties:
+
+             1. On input, it will be '1' if the I/O expansion board is
+                present.
+             2. Setting it to an output of '0' will generate a system reset.
+             3. Setting it to an output of '1' will not only illuminate the
+                LED take the card out of reset and enable power to the SD
+                card slot.
+
+             As a consequence, the GREEN LED will not be illuminated if
+             SD card support or SPI is disabled.  The only effect of
+             CONFIG_ARCH_LEDS is that the GREEN LED will turned off in
+             the event of a crash.
+
+  D1 AMBER:  Controlled by the on-board MCP2221A USB bridge and provides USB
+             enumeration status.  Not under eZ80 control.
+
+Buttons
+-------
+
+  The MakerLisp CPU board has no on-board buttons that can be sensed by the
+  eZ80.
+
+Configurations
+==============
+
+Common Configuration Notes
+--------------------------
+
+  1. src/ and include/
+
+     These directories contain common logic for all MakerLisp
+     configurations.
+
+  2. Variations on the basic MakerLisp configuration are maintained
+     in subdirectories.  To configure any specific configuration, do the
+     following steps:
+
+       tools/configure.sh [OPTIONS] makerlisp/<sub-directory>
+       make
+
+     Where <sub-directory> is the specific board configuration that you
+     wish to build.  Use 'tools/configure.sh -h' to see the possible
+     options.  Typical options are:
+
+       -l Configure for a Linux host
+       -c Configure for a Windows Cygwin host
+       -g Configure for a Windows MYS2 host
+
+     Use configure.bat instead of configure.sh if you are building in a
+     native Windows environment.
+
+     The available board-specific configurations are  summarized in the
+     following paragraphs.
+
+  3. This configuration uses the mconf-based configuration tool.  To
+     change this configurations using that tool, you should:
+
+     a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
+        see additional README.txt files in the NuttX tools repository.
+
+     b. Execute 'make menuconfig' in nuttx/ in order to start the
+        reconfiguration process.
+
+Configuration Subdirectories
+----------------------------
+
+  nsh:
+
+    This configuration builds the NuttShell (NSH).  That code can be
+    found in examples/nsh.  For more information see:  examples/nsh/README.txt
+    and Documentation/NuttShell.html.
+
+    NOTES:
+
+    1. A serial console is provided on UART0.  It will be necessary to
+       connect either a TTL-to-RS232 or a TTL-to-USB Serial adapter to CN1
+       pins 59 and 61.

+ *         implementation without modification.  The argument has no
+ *         meaning to NuttX; the meaning of the argument is a contract
+ *         between the board-specific initialization logic and the
+ *         matching application logic.  The value cold be such things as a
+ *         mode enumeration value, a set of DIP switch switch settings, a
+ *         pointer to configuration data read from a file or serial FLASH,
+ *         or whatever you would like to do with it.  Every implementation
+ *         should accept zero/NULL as a default configuration.
+ *
+ * Returned Value:
+ *   Zero (OK) is returned on success; a negated errno value is returned on
+ *   any failure to indicate the nature of the failure.
