Description of problem:
Well, automake and autoconf should be added to the BuildRequires
of gettext as now a patch is applied which causes the need (try
to rebuild gettext without automake/autoconf).

Version-Release number of selected component (if applicable):
gettext-0.14.1-3

Expected results:
Something like my solution or without the conditional things...

Additional info:
I think, the conditional is better, because the patch applying is 
only at AMD64 really needed.
