Original commit message from CVS: * m4/Makefile.am: And a couple more .m4 that don't exist anymore with gettext 0.17
All aclocal .m4 files we need are put here and cat'd to acinclude.m4 in the source root. Official ones (taken from the relevant devel packages) are named as-is, unofficial ones (or changed ones) get a gst-prefix.
