Seems to have been in ~arch for ages so please test if it's good for stable. Noticed while removing built_with_use usage from maintainer-needed stuff.
Sparc stable.
amd64 stable
x86 stable
Stable for HPPA.
ppc stable
ppc64 stable
alpha/arm stable. Adding ppc/ppc64 since they weren't cc'ed
Err, well, ppc* didn't commit it properly, i guess because the EAPI 2 stuff. Brent: you need to use portage-2.2_rc11 to commit this.
ppc/ppc64 stabled with an unstable portage :|
