Summary: _socket fails to build on IRIX 6.5

Initial Comment:
Building 2.2a1 on a 64-bit SGI box running IRIX 6.5.  I
 used the MIPSPro 7.30 compiler, using the "-n32" flag
("new 32-bit object").  Building the interpreter and
most extensions works, but creating _socket.so fails as
 follows:

ld -shared -all
build/temp.irix64-6.5-2.2/socketmodule.o
-L/usr/local/ssl/lib -L/usr/local/lib -lssl -lcrypto -o
build/lib.irix64-6.5-2.2/_socket.so
ld32: FATAL   12 : Expecting n32 objects:
/usr/local/ssl/lib/libssl.so is o32.
WARNING: building of extension "_socket" failed:
command 'ld' failed with exit status 4

I think this is a local configuration error, but the
build process should probably be more resilient to it.
At the very least, there should probably be a
--without-ssl configure option so linking against
OpenSSL can be disabled on systems with broken OpenSSL
installations (like this one).

Oh, I forgot to mention: I worked around the problem by 
editing setup.py.  In PyBuildExt.detect_modules(), I just 
commented out all the code that looks for OpenSSL, so 
_socket.so is always built from socketmodule.c alone, with 
no other junk (eg. broken SSL libs).

This build failure happened because /usr/local is broken 
on the system where I tried to build it.  (Briefly, 
/usr/local is full of 32-bit libs from IRIX 5, and I'm 
building on 64-bit IRIX 6.)

The main Python problem here is lack of flexibility in 
setup.py: it always adds /usr/local/{lib,include} to the 
library/include search paths, and always looks for OpenSSL 
in /usr/local/lib.  If /usr/local is broken or 
untrustworthy, this is the wrong thing to do.

This has nothing to do with the _socket module per se, 
though, so I'm going to close this bug.  I'll see if I 
can't come up with a patch to add options to setup.py, eg. 
"--without-openssl" or "--without-usrlocal".
