devel/imake-cf: use gccmakedep on all architectures

Previously, gccmakedep(1) was incidentally enabled by way of including
<xorg.cf> on those architectures for which an old configuration
existed for building the X11 server.  Other archs would fall back
to using makedepend(1) for Makefile dependency generation.
