'K, but apparently right now we are broken on Opteron/Itanium without this
patch ... so, to fix, we either:

a. add appropriate tests to the individual port files based on individual
failure reports (albeit not clean, definitely safer), or:

b. we do massive, sweeping changes to the whole HAVE_TEST_AND_SET
detection code (definitely cleaner, but has potential of breaking more
then it fixes) :(

personally, as late in the cycle as we are, I think that a. is the wiser
move for v7.4, with b. being something that should happen as soon as
possible once we've branched and start working on v7.5 ...
