Summary: --with-shared: python with shared lib

Initial Comment:
As a follow up to patch 400938
(https://sourceforge.net/tracker/?group_id=5470&atid=305470&func=detail&aid=400938),
here is an implementation of the --with-shared
configure option for building python on Posix systems
as a shared library.

Building python as shared library is activated with the
--with-shared option on ./configure

The following points are drawn to particular attention:

- A configbuild.py module is generated and placed in
the machine-dependent directory. It records most 
Python/Makefile variables (CC, CFLAG, LDSHARED...), and
make them available in Python.

- The build has been tested on:
   Linux2: OK
   SunOS5: OK
   IRIX64: Build OK, crash on test (bus error)

- Inference with distutils: I found it very difficult
understanding the distutil architecture and finding the
right points of change; I minimized my interaction
there. Furthermore, the availability of the
'configbuild' module overlaps some of the distutils;
but 'configbuild' is very easy to use ...

- Unresolved symbols: I turned on the symbol checking
flags whenever possible, on behalf the its better
generating the error on build than at runtime.

- configure.in: I only edited the configure Bourne
script, and did not bother with configure.in (actually,
I deleted it) and its autoconfig/m4 macro comparses.

Haven't seen the patch yet, but I like the idea -- the
command line option suggests that it shouldn't hurt
platforms where it can't be done or has to be done
differently.

Alternative: we could also consider using libtool. I didn't
like that much in the past, but maybe it would work. Dunno.
Anybody know about it?
