Will that take precedence over qemuall though? Sounds brittle. Another
option is to make the fbdev configuration specific to mips and arm, as
using kms does not need a configuration at all.
I think it will. arch specific overrides should come before generic ones.

non-x86 qemu, and kms backend is using software renderer in mesa. So
fbdev is the only realistic option there. But for x86 qemu kms is
still viable. I'm not sure how to best configure it though.
copy qemuall/weston.ini new folders qemux86 and qemux86-64 and point
to backend it should be using.
