I tried it both ways, using C source, and also using assembler on
two different versions of ppc64le Fedora, Fedora 35 and Fedora 32.

Testing showed one pass for each of the runs when using builds against
recent upstream sources (w/ your fix).  When tested against the
installed GDB (which does not have your recent ppc related fix), the
tests correctly showed 1 failure per run.

I like this test better!
