local:64-bit-bfd:sys-libs/binutils-libs: Support 64-bit targets even on 32-bit hosts This flags doesn't seem to be meaningful on 64-bit hosts, and furthermore seeing USE=-64-bit-bfd by default makes people wtf. I think it should be p.use.forced on those arches to make the meaning explicit.
i've clarified the USE flag behavior: http://gitweb.gentoo.org/repo/gentoo.git/commit/?id=5389c4dc429b9f43975a0f5eb9f0a6227bf9af30 tracking "is 64-bit" is too much of a pain in the profiles
