We have tons of hand-crafted pixel shuffeling code all over the place
which I want replace with pixman library calls.  It's a long road and
will take quite some time.

I wanna have pixman as core service in qemu for that, not some optional
add-on.

We pass on cross-prefix to pixman's configure, so it should
JustWork[tm].  And it actually works for windows cross builds using the
mingw toolchain.  If it doesn't work for your setup I'd much prefer to
fix that.

I run qemu on headless machines alot, then connect via vnc/spice ...
