Ok, so basically, you will probably need to do a few things here to get
that fixed I guess:
  - In libxml2, remove the --without-python option if python emulator is
selected
  - Make the mesa3d package depends on host-python and host-libxml2 (I
guess?) (basically, just add these two packages to MESA3D_DEPENDENCIES)
  - Make mesa3d use the host-python package we just built instead of the
one found on our distribution

I guess something like that would work. But what are the others think on
making mesa depends on host-python? It looks a bit oe-ish, but I don't
quite see a better way.
