Subject: [kvm-unit-tests PATCH 31/32] powerpc: Remove remnants of ppc64 directory and build structure

From: Nicholas Piggin <[email-masked]>
Date: Mon, 26 Feb 2024 20:12:17 +1000

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.
