Well, the "don't select GCC 6" changes unmasked another issue that's
still there, as I touched on a bit in the other email thread here. For
now, I restored the GCC 6 handling that was there and left your other
changes as-is. I tested this fixed the issue on 8.2_STABLE and didn't
cause any issues on 9.2_STABLE (not that that would have been happening
before, either). That is a bit of a kludge, except, if we can use GCC 6
in some circumstances, that handling code should be there anyway.

The way the code handles certain aspects of versioning and decisions
seems to need further investigation. At a minimum, more comments would
help. I'm too burned out at the moment to tangle with it.
