glibc: Explicitly disable msgfmt

If configure is rerun it finds msgfmt from gettext-native which is installed
during package_write_ipk|deb and means builds are not determinisic.

Whether msgfmt is needed is debatable (libc.mo files aren't generated without
it), however, we should at least be consistent which this patch ensures.
