cross-recipes: Disable nls in gettext bbclass

Right now for cross recipes e.g. gcc-cross and binutils-cross
we specify --disable-nls .... --enable-nls on configure cmdline
the --enable-nls coming from gettext bbclass.

So we disable nls for all cross inheriting recipes in gettext
bbclass and then we remove the extra --disable-nls in gcc-cross
and binutils-cross

This patch needs testing. Please help
