[kvm-unit-tests PATCH v8 34/35] powerpc: Remove remnants of ppc64 directory and build structure

Nicholas Piggin
2024-04-05T08:38:12Z

This moves merges ppc64 directories and files into powerpc, and
merges the 3 makefiles into one.

The configure --arch=powerpc option is aliased to ppc64 for
good measure.
