I've started this process already.  I think a useful search order is

1) next to current setup.py  --- os.getcwd() is probably better than 
what I did (backing up the frame until you can't go back anymore and 
getting the __file__ from that frame).  Incidentally, it looks like a 
site.cfg present there is already copied to numpy/distutils on install 
--- it's looks like its just not used for the numpy build itself.

2) in the compilers "HOME" directory --- not sure how to implement that.

3) in the system-wide directory (what is currently done --- except when 
you are installing numpy that means it has to be in 
numpy/distutils/site.cfg).

I created a get_site_cfg() function in system_info where this searching 
can be done.   Feel free to change it as appropriate.
