A complete set of packages from emul-linux-x86-xlibs has been committed
to the 'multilib' branch of X11 overlay for testing.

So, if you're using live xorg and would like to test this, you should:

$ cd /var/lib/layman/x11 # or any other location
$ git checkout multilib
$ emerge -1v emul-linux-x86-xlibs

It shall pull in -r1 version which replaces the bundled libraries with
a bunch of multilib package dependencies.
