I just want to mesa-xlib only for qemumips/qemuppc/qemuarm.

You mean add "xserver-xorg-lite" as preferred virtual/xserver in 
meta/conf/machine/qemumips.conf?

I think this requires: emulated graphic HW capability in qemumips/qemuarm, and 
an drm driver to match the emulated HW. With them, we can turn on "enable-dri" 
for mesa-dri and fight the build issue.
