Would something like an unpack.mask/UNPACK_MASK="paths/ wildcards.."
work for you? Perhaps you can simply just take advantage of tar's
--exclude=/-e options in the unpack() function of ebuild.sh when
USERLAND == GNU. Untested patch attached if you want to play
with/perfect the idea. By excluding it from tar you should be able to
save space/cpu/ram all the way around the board while getting the same
end result.
