The ctypes findLib stuff for 'os.name == "posix"' was written by Andreas Degert,
he used fancy calls to gcc, /sbin/ldconfig, and objdump to find the shared lib
that would be used for the linker's -l<libname> flag.  Apparently this only works
on *some* systems.  On OSX, Bob Ippolito's macholib is used.

If someone could implement this for other systems it would be great, otherwise
it would probably be best to enable this test only on linux .
