[Bug bootstrap/19607] New: Build fails on MSYS/MingGW because of incorrect SYSTEM_HEADER_DIR

["guardia at sympatico dot ca" <gcc-bugzilla at gcc dot gnu dot org>]

On MSYS, the system headers are found in /mingw/include ... I made a modified
gcc/config/i386/t-mingw32 adding:

NATIVE_SYSTEM_HEADER_DIR = /mingw/include

And it works here.

Also, the configure script needs to be started with a relative path or the
"srcdir" anyway needs to be relative or gengtype will fail. This problem is
documented in bug #16024 (gengtype doesn't crash here, but it still fails not
finding a path)
