include/cxx contains NuttX's mini C++ ABI shims and must only be added
to the include path when CONFIG_LIBMINIABI is selected. tools/Config.mk
was adding it unconditionally for every non-LIBCXX/non-UCLIBCXX build,
and the platform.cmake files for arm, arm64, risc-v, x86_64 and tricore
were adding it inside the CONFIG_LIBCXXTOOLCHAIN block.
With an unpatched downloaded ARM GNU Toolchain, <cstdlib> uses
newlib's stdlib.h, defining div_t as an anonymous struct. A later
inclusion of NuttX's stdlib.h via <cstdio>->stdio.h->kmalloc.h then
redefines div_t with struct tag div_s, causing a conflicting declaration
error.
Guard the div_t/ldiv_t/lldiv_t definitions in stdlib.h with
redefinitions when a toolchain stdlib.h was already processed.
Also fix lldiv_s members typed as long instead of long long.

Reduce the downloads of esp-hal-3rdparty when using nxtmpdir to store
esp-hal-3rdparty and speedup compilation after `make distclean`.
Usage:
```
~/nuttxspace/nuttx/make distclean
~/nuttxspace/nuttx/./tools/configure.sh -l -S esp32-devkitc:nsh
~/nuttxspace/nuttx/make flash -j 8 ESPTOOL_PORT=/dev/ttyUSB0
~/nuttxspace/nuttx/picocom /dev/ttyUSB0 --baud 115200

Fix an issue that math library header files are not exported by make export.
Create symbolic links of libmcs, newlib and openlibm header to nuttx/include.
To solve the issue of carrying object files from previous builds,
Matias changed the archiving process to re-archive libapps.a on every compilation,
if libapps.a carries more object files, incremental compilation will waste too
many time in re-archiving, compared with the previous implement, this is a degradation
of the build system. Referring to mature engineering projects such as cmake, if there
is configuration or source file changed, the best solution should be to reconfigure
the environment.
Revert this PR to ensure the compilation speed during incremental compilation.

| Fix: ensure archive files do not carry object files from prior builds
|
| In some cases, when NuttX configuration changes and this makes the
| object list used to build one of the .a libraries change as well,
| since the command used to build it is "ar crs" and this simply appends
| the list of object files, the library could still include object
| files from prior builds. This commit modifies the ARCHIVE macro to
| erase the .a file if it already exists.
|
| Since in some cases this behavior was actually expected (object
| files from a subdirectory were appended to a library created one
| level above) I added a ARCHIVE_ADD which works as ARCHIVE did.
|
| This change should greatly improve behavior of building after
| configuration changes.

Add PREBUILD definition and `prebuild` recipe to call it before
the `mkconfig` tool, at the beginning of the build process. This
`prebuild` step enables running CPU/board-specific operations
before building the firmware, like tweaking or overriding configs
that need to be set after the board configuration.
Summary:
- I noticed that the following build error happened on my machine.
