Fix initscripts in recommended programs flag
Fix usage of make.conf

Modern portage uses only /etc/portage/make.conf.
We don't want this overwritten by our custom version since
host-independant variables (e.g. CHOST) are set.

Append our custom file to the real file, and remove the custom one
(since it is duplicate).

ALso fix calls to dracut modules as it checked for the file which
shouldn't exist.
Update keywords

gcc-4.6.3 is stable now, not needed.
