(I haven't read this whole thread yet, but in case it hasn't been
mentioned:)

It's also worth pointing out that the whole reason why abi_x86_32 is
{package.,}use.stable.masked is because trying to manage the partial
transisition between emul-* and multilib-build dependencies on stable
or mixed-keyworded systems is a horrible headache at the moment, due
to those exact same unexplainable dependency errors.  Without
{package.,}use.stable.mask, all stable users would have to deal with
this *right now* on their systems.


Note also that setting ABI_X86=32 globally isn't how it's supposed to
be used; the point of this flag is for dependency resolution when a
particular package requires it (ie, top-level package depends on
app-cat/dep[abi_x86_32], portage --autounmask-write sets the necessary
changes to /etc/portage/package.use).  But that's neither here nor there.
