    acinclude.m4: Rip out crappy python-finding code and just use pkg-config
    
    The code for trying to find the Python library is not multilib (lib64)
    aware, and besides that is just plain hideous.
    
    We already hard require pkg-config installed to find pygobject, so
    use it for Python too.  (If python.pc doesn't come on Windows, pygobject
    should really start shipping it, because they can't link to different
    versions of Python).
