simbit18 d16de91e39 [MSYS2] CMake+Ninja Fix arm-none-eabi-ar: Argument list too long
This issue is related to the Arm toolchain for Windows which is available for x86 host architecture only (compatible with x86_64)

Windows (mingw-w64-i686) hosted cross toolchains
AArch32 bare-metal target (arm-none-eabi)

Issue
/bin/sh: line 1: /home/nuttx/nuttxnew/tools/gcc-arm-none-eabi/bin/arm-none-eabi-ar: Argument list too long

On Windows, arm-none-eabi-ar can only accept strings up to a maximum length of 32,768 characters.

We could suppress the 32K include string limitation by setting the CMake variable CMAKE_NINJA_FORCE_RESPONSE_FILE to ON.

This is unfortunately not enough!!! ): In the build phase this error comes out

$ cmake --build build

The Workround I found to solve this problem is to overwrite
the responsible file flag CMAKE_${lang}_RESPONSE_FILE_FLAG with $DEFINES $INCLUDES $FLAGS

Maybe there is a better solution but this one it works. :)
