So the failure is that swrast is no longer shipped by mesa but the
qemu BSP does this:

XSERVER ?= "xserver-xorg \
            ${@bb.utils.contains('DISTRO_FEATURES', 'opengl',
'mesa-driver-swrast xserver-xorg-extension-glx', '', d)} \
            xf86-video-fbdev \
            "

However as Alex says, we have virgl now.  Does this work on all qemus?
 Should we just change the XSERVER assignment to explicitly pull in
the megadriver instead?

The 'proper' swrast driver *is* terrible, lets not enabe it by default
now we have virgl for qemu.  If a BSP wants to use it then they can,
but it's not something we should enable out of the box.
