Actually, in Fedora, it is.  We work closely with upstream.  If you
patch the correct semantic level, you can send the patch back to
upstream for incorporation.  If you only patch the configure script you
aren't helping upstream to improve their code.

Also, patching the configure script, while easier fixing the things the
majority of times that you've had to fix the build scripts is just
anecdotal.  My own anecdotes are skewed in the other direction -- I
can't recall one time that I've needed to patch the configure.ac script
where it would have been easier to patch the configure script directly
instead.  Introducing side-effects is something to watch out for but
patching configure instead of the true source is a short term fix, not a
long term solution.
