[yocto] udev-hwdb - post installation error (PPC target)

[Gaurang Shastri]

Hi

I have added systemd as my DISTRO_FEATURES for one of my ppc target.

But in my log.do_rootfs, I can see that for "udev-hwdb" RPM, generated from
"systemd", post-installation script failed with core dump:
{{{

>From the above, it is clear that we are missing correct "QEMU_OPTIONS"
while passing through "qemu-ppc" binary in qemu.bbclass. I am able to make
it working with following patch:

Please check the above and let me know so that I can send the patch in
correct format (via filing a bug and attaching as regular patch format)
