Subject: Pass `-MG' to `gcc' in the generated `makegen-cc' script.  The meaning

Pass `-MG' to `gcc' in the generated `makegen-cc' script.  The meaning
of `-MM' was changed in recent versions of GCC so that it does not
mask errors about absent system headers, but with `-MG' it uses the
old semantics.
