classes/qemu: use tune to select QEMU_EXTRAOPTIONS, not package architecture

Using the package architecture to select the right qemu options to pass
to qemu-user is incorrect, and fails for recipes that set PACKAGE_ARCH
to MACHINE_ARCH (as the qemuppc workarounds suggest) because there are
not typically any options set for the machine name.

Solve this by using TUNE_PKGARCH instead: for the majority of recipes
this is the same value, but for machine-specific recipes it remains the
same instead of changing to the machine name.

This means we can remove the qemuppc workarounds, as they're obsolete.

Also update the gcc-testsuite recipe which uses the same pattern to use
TUNE_PKGARCH, and generalise the else codepath to avoid needing to
update the list of architectures.
