Just to clarify, I certainly wasn't objecting to a patch that tries a
generic build first and only then moves on to do probes!  I've been
wanting that for a long time.  I was just saying that the error messages
in config.log have generally been enough for me to figure out what was
going on.

The patch sounds like a great idea to me, and I'll try to take a look at
it sometime today in penance for not understanding what you were getting
at the first time.  :)
