I wonder if there's a way to run it SMP ..-ish..

How is SMP going to change the number of processes to be run?

Most of the tests in a configure script don't actually have to run in series.

Writing the code to analyze all the tests and build a dependency graph would be pretty tricky, though. Getting portable shells to launch N tests in parallel (where N is probably cores * 1.5 or so) at a time and integrate the results would be even trickier. You could do it easier in, say, Erlang, but then you've thrown portability out the window.
