Sebastian Huber f9648baf65 bsps/arm: Add support for small pages MMU 
The small page MMU support reduces the granularity for memory settings
through the MMU from 1MiB sections to 4KiB small pages.

Enable it by default on the realview_pbx_a9_qemu BSP.

Bug was introduced by commit 1e1afa3779.

Hesham Almatary f462bcbb0a riscv: Address differences in the linkerscript between GNU LD and LLVM/LLD 
LLVM/LLD does not support STARTUP and ALIGN_WITH_INPUT directives that
GNU LD support. INPUT and ALIGN(8) are supported by LLVM/LLD and can
replace the unsupported STARTUP/ALIGN_WITH_INPUT directives.

The commit conditionally adds the supported directive that linkers
can understand depending on the toolchain used to compile RTEMS
i.e., clang or gcc. Clang is assumed to use LLD by default.

Chris Johns 270c5df5db Makefile.inc: Add support for staged builds. 
- Allow the RTEMS_ROOT to be conditionally supplied. This
  can be a staging area before being moved to the final
  install prefix location.

- Update the default.cfg to use RTEMS_ROOT and to not rely on
  the exec_prefix so it's paths can be staged.

- Fix and add the needed configure subs.

Closes #3768

Sebastian Huber 0a1f5df98e Simplify _CPU_Counter_difference() 
In order to simplify the use of CPU counter values it is beneficial to
have monotonic increasing values within the range of the CPU counter
ticks data type, e.g. 32-bit unsigned integer.  This eases the use of
CPU counter timestamps in external tools which do not know the details
of the CPU counter hardware.  The CPU counter is the fastest way to get
a time on an RTEMS system.

Such a CPU counter may be also used as the timecounter.  Use it on SPARC
for this purpose to simplify the clock drivers.

Update #3456.

Jacob Hansen 5cbc9c5922 clang: Keep -qrtems and -B for compilers without -specs support 
This is needed for building rtems correctly with Clang.

Note that this change does not mean rtems can build correctly with
mainline clang. However the change allows building rtems with a
Clang toolchain that has a rtems frontend similar that of GCC's
builtin rtems specs.

Amaan Cheval bc7313134f bsps/x86_64: Add APIC timer based clock driver 
The APIC timer is calibrated by running the i8254 PIT for a fraction of a
second (determined by PIT_CALIBRATE_DIVIDER) and counting how many times the
APIC counter has ticked. The calibration can be run multiple times (determined
by APIC_TIMER_NUM_CALIBRATIONS) and averaged out.

Updates #2898.
