That's a good question, and now I realize that I could have given more
information on the commit message (fixing it).

The core issue is that when running tests and a QEMU binary is not
explicitly chosen, we pick one first from the build tree (then from
system) that matches the host architecture.

Without such a mapping, when running tests say on a host arch ppc64le, a
QEMU binary will not be found.  This was first mentioned here:
