I've had issues with the 2 locations for configure.log [for eg: in the
nightly builds] - so 1 location $PETSC_ARCH/conf is good for me.

But one potential problem: I don't think it can be directly built in
$PETSC_ARCH/conf as $PETSC_ARCH is sometimes determined quarter-way
through the configure process [and the dir $PETSC_ARCH/conf is created
then..]

So the logfile should get copied over at the end... [I'd like to keep
a link in PETSC_DIR to the latest configure.log - and perhaps make_log
aswell]
