Filing this bug as the stabilization will be necessary in order to unmask abi_x86_32 on amd64-stable. Note also that x11-libs/libSM-1.2.1-r1 and x11-libs/libSM-1.2.2 will need to be masked/removed due to their having a hard-dep on emul-linux-x86-baselibs.
Please continue in the pending bug. *** This bug has been marked as a duplicate of bug 530652 ***
