The remaining issue is that the just built compiler under test looks in
the install location.  I.e. bogus files from a previous borched install could
cause failures, or a missing file in the build could be masked by having the
file in the install location.
There are ways to manage this issue, like always picking a new, un-populated
install location for test builds.  That's what I usually do now, so this
problem affects me no longer.
OTOH, if such a test methodology is generally used, we run the risk that
building with a populated install location will bitrot.
