[PATCH] Fix gcc_release to not build GO tarballs on old branches

[Richard Guenther]

This changes maybe_build_tarfile to require that the first directory
in the list actually exists.  This avoids building a GO tarball on
old branches where neither gcc/go nor libgo exist but libffi does.

I have built the 4.5.3 release candidate with this patch applied.

Looks ok?

Thanks,
Richard.
