Alexander Kanavin 7561eb32a0 qemu: enable virglrenderer and glx options subject to 'opengl' DISTRO_FEATURE
Note that to actually use accelerated GL passthrough, there are two options

1) a suitable frontend need to be also enabled - gtk+ and SDL both seem to work well.
Previously I struggled to make SDL work, but now it seems fine.

2) it is also possible to render off-screen with -display egl-headless option,
and see the output with a VNC viewer (for which, qemu needs to be started
with a VNC server):

$ runqemu kvm egl-headless publicvnc

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
