1 progress update:
2 - binutils-2.22 in ~arch should work fine
3 - glibc-2.14.1-r1 in ~arch includes support when "x32" is in MULTILIB_ABIS
4 - linux-headers-3.1 includes support when "x32" is in MULTILIB_ABIS
5 - you'll still need gcc-4.7 from the toolchain overlay
6 - a 3.1 kernel can be obtained here:
8 the only problem is with bootstrapping. there is no way atm to live migrate
9 between multilibs on your system. this isn't a new problem ... we've been
10 punting all bugs where people try to go from MULTILIB_ABIS="amd64" to "x86
11 amd64" on a live system. same issue applies when adding "x32" to the list.
13 i've been contemplating how to address this, but so far, it seems like the
14 easiest is to post a glibc binpkg which includes all possible ABIs and have
15 people install that first. then they should be able to install gcc/linux-
16 headers freely and rebuild glibc after that.
