Incoming gnustep-make parallel support

When I add gnustep-make-2.2.0 to portage, repoman (our QA and commit tool) will at last be happy, as from this version, it won’t be necessary to force -j1 make flag! This will also allow parallel make for all gnustep packages in our tree(as the gnustep eclass forces -j1). No need to sync again and again your portage tree, this version is not yet released 😉 Original announcement is here

Some other entries on my gentoo/gnustep TODO list: the Etoile packages in the gnustep overlay need some cleanup (some keywords should be dropped for example Melodie player, maybe bump llvm to 2.5, but I hope some other dev will look into it before me), and updates when 0.4.2 will be released, gnustep packages, fix AC_CANONICAL_TARGET usage found in most of gnustep-base packages (thanks Flameeyes for finding more work for us 😉 ), and filter -Werror in some of our packages (helps when switching to newer GCC for example),
