Add some temporary autoconf checks to try to figure out why test_math is
failing on Debian/alpha. (log(9.88e-324) gives an unexpected ValueError on that platform). These checks will be removed again once the source of the problem is identified. I hope this is a reasonable way to approach the Debian/alpha buildbot failures; if there's a better way of debugging buildbot test failures then please let me know.
