Merge Funtoo 1.0 profile support into gentoo

Steps to merge funtoo 1.0 style profile support into gentoo:

1.) eselect-profile support

   We want eselect-profile to support both the funtoo style profiles and the gentoo style profiles at the same time
   First thought, says if /etc/{,portage}/make.profile is a symlink, only show gentoo style profiles; this will hide the changes from unsuspecting users so they don't     
       accidently set an experimental profile as gentoo tries to catch up.
   If /etc/{,portage}/make.profile is not a symlink, then show a list of old style profiles and new style profiles.
       This may require funtoo to remove profiles.desc and profiles.eselect.desc from gentoo before replicating.

2.) catalyst support

   seems trivial, support catalyst setting new style profiles.

3.) build prototype profiles in gentoo for all possible x86/amd64 varients.
