Gentoo x32 release candidate

[Mike Frysinger]

i'm pleased to announce the initial x32 release candidate:
http://dev.gentoo.org/~vapier/x32/stage3-amd64-x32-20120605.tar.xz

the x32 ABI is the default one, and includes x86/x86_64 ABIs

i call this a release candidate as it is using glibc-2.15 with
backported patches. the ABI however should be the same as glibc-2.16,
so hopefully the upgrade will go smooth. but i don't want to make an
official release on the chance that things aren't smooth, so this is a
release candidate.

once glibc-2.16 is released upstream, we should have x32 stages
released alongside the existing x86/amd64 stages.

caveats:
- you have to be running linux-3.4+ with the x32 ABI enabled in your config
- the x32 profile has marked toolchain packages stable ahead of other arches:
- linux-headers-3.4
- binutils-2.22
- glibc-2.15 (and will have stable glibc-2.16)
- gcc-4.7.0
- strace-4.7
- gdb-7.4.1
- gdb will probably be flaky, but the new gdb-7.5 release should address that

so if you try running stable amd64, you will hit some failures
unrelated to x32, but related to the newer toolchain packages. this
will get better over time as other packages go stable, and i'll be
trying to push at least binutils/linux-headers stable soonish.

for the adventurous souls, please review the existing x32 tracker bug:
https://bugs.gentoo.org/show_bug.cgi?id=x32
and file new bugs for packages you come across that aren't yet known

to be kind to Gentoo infra, i've put this on our mirrors:
http://distfiles.gentoo.org/experimental/amd64/x32/

this URL will continue to work as i setup an apache redirect, but
please use the new one anyways
