Subject: [Bug target/56279] Unwanted directory is added to include search path when building for MingGW with --native-system-header-dir

This unwanted dir is added by blindly overriding directory in
gcc/config/i386/mingw32.h:

#undef NATIVE_SYSTEM_HEADER_DIR
#define NATIVE_SYSTEM_HEADER_DIR "/mingw/include"

as result of fixing bug 52947. I think, it needs more improvement. At least for
MinGW this directory should be relative to GCC files, as other include dirs.
And cppdefault.c should be corrected like this:

#ifdef NATIVE_SYSTEM_HEADER_DIR
    /* /usr/include comes dead last.  */
    { NATIVE_SYSTEM_HEADER_DIR, NATIVE_SYSTEM_HEADER_COMPONENT, 0, 0,
      NATIVE_SYSTEM_HEADER_DIR_ADD_SYSROOT, 0 },
#endif

similar to GPLUSPLUS_INCLUDE_DIR part in cppdefault.c.
