Summary: Enable crosscompilation

Initial Comment:
 
Python is awful to crosscompile. I've done it with the help of that 
site ( 
http://www.ailis.de/~k/knowledge/crosscompiling/python.php), but 
I still had to patch the setup.py myself. 
 
The wish: 
 
Could you avoid to add the standard include path (usually 
/usr/include) to the include paths (in setup.py)? It confuses my 
crosscompiler (for which /usr/include isn't applicable, because it 
produces code for a different plattform and endianess), because 
the includes given by commandline to the gcc are searched 
before the standard include paths. And if there are files with the 
wished names, it will produce lots of errors and warnings. 
 
The second one (a more longterm wish) 
 
Could you split the build process into 2 parts? A part which is 
plattform independet (the (cross-) compilation of the python-binary 
and all required binary libraries), and a plattform specific one, 
which is then running on the target plattform. 
This would help me and other people crosscompiling python for 
more plattforms and embedded systems, which haven't an 
available native compiler (or the plattform isn't suppossed to run a 
compiler because of its limited ressouces).

I've already have a patch (which is mostly a port of
http://www.ailis.de/~k/knowledge/crosscompiling/python.php
to the current version), and extended it further, so it
compiles now really all modules.

The compilation itself isn't as simple anymore as
./configure
make 
make install

I can submit a simple patch, which enables setup.py to get
some  information of the environment instead of distutils.
These patches aren't nice (in fact I would call them a
really hack), especially the patched Makefile.

I'll will do it tomorrow morning, but don't expect to much
from it :-)

I don't think anyone would take issue with supporting
cross-compilation.  Your requests seem reasonable, although
not necessarily easy.  :-) However, I don't think many
(any?) developers cross-compile.  Probably the only way to
support cross-compilation would be if you could produce a
patch.  Even a patch that solves part of the problem could
be beneficial.  How would you like to make a patch?
