Brad King 3c2ecbe74e Add alternate per-vendor compiler id detection
At least one Fortran compiler does not provide a preprocessor symbol to
identify itself.  Instead we try running unknown compilers with version
query flags known for each vendor and look for known output.  Future
commits will add vendor-specific flags/output table entries.
