Well, perhaps this is business as usual, but I'd still like to understand this
a little better.

What causes us to run the effective-target check for this thing in the first
place?  

I've restricted my query with RUNTESTFLAGS to directories that contain
powerpc.exp.  To my knowledge, there's nothing in any such directory that cares
about GPU offloading.  So what causes the effective-target check?

I'm okay with closing this, but would very much like to understand if we have
an inefficiency here where we're running all sorts of checks that aren't needed
for the tests being run.  Or if we have something wrong in powerpc.exp that is
causing this unnecessary effective-target check.
