Details:

I ran into problems building Octave using homebrew on mac osx 10.9. The
problem boiled down to the fact that the test for unordered map in
configure.ac omitted the template parameters, and thus the test failed for the
wrong reason. Rather than describing the problem in detail, I'll submit the
following patch for configure.ac, which should hopefully be self explanatory.

Thanks!
