Thinking about this some more, I'd rather *not* include the platform or
architecture in the tag by default.  They aren't really necessary to support
the instigating use case and will probably be fairly uncommon.

I'd be okay including a configure option to allow you to add whatever you want
after the implementation, version, and flags.  E.g. something like:

    ./configure --with-abi-tag-extension=linux2

would lead to foo.cpython-32m-linux2.so, so not the nicer names we'd prefer
but probably good enough for your purposes.

Would that work for you?
