 Apologies for the curious title...

 This is a feature request for those of us who build GCC from source. At
 the moment we end up building everything twice because of the fact that
 port:gcc depends on port:libgcc .

 I'm not questioning the benefits of that interdependency but I think it
 wouldn't be particularly hard to refactor the Portfile in such a way that
 users who build from source can opt to merge the port:libgcc payload back
 into port:gcc and turn port:libgcc into a "stub".

 That won't change anything for regular users (who only need port:libgcc)
 nor for the ports declaring a dependency on libgcc. The only visible
 change on disk would be small, partial role-reversal: instead of port:gcc
 installing symlinks to content from port:libgcc, it would be port:libgcc
 installing symlinks to libraries installed by port:gcc .

 I'm currently tinkering with GCC anyway so I can volunteer to do the
 necessary refactoring - once Ryan has upgraded the GCC ports to take the
 7.1 release into account.
