I'm sorry I didn't get around to looking at this today.  My recollection
is that traditionally the way we've done multilib support is to patch
python so that arch-specific files go below {_libdir}, but
arch-independent files go below /usr/lib.  IIRC I did something like
this for our build of python 2.7 so that it looks in the correct place
for the Makefile.

See
http://pkgs.fedoraproject.org/gitweb/?p=python.git;a=blob;f=python-2.7rc1-lib64.patch;h=9462e829282b3a66ae8306e0290769076aa5d05f;hb=HEAD
(distutils)

and:

http://pkgs.fedoraproject.org/gitweb/?p=python.git;a=blob;f=python-2.7-lib64-sysconfig.patch;h=0cef36192330c023a80b59388920a6ca6b6f8c06;hb=HEAD
(sysconfig).

(These patches are applied only on 64-bit builds).

Note that in the latter I kept "purelib" to be /usr/lib, whereas
"stdlib", "platstdlib", and "platlib" I patched to use %{_libdir}.


Hope this makes sense
