While installing on PyPy, zope.interface should not build the C extension

[fijal]

It used to be the case that PyPy simply didn't manage to compile the C extension and everything was fine. However, recently it started working, but the extension is not running. It builds fine and then segfaults. Since it's for speedup reasons only, there is no reason to use it in PyPy at all - even if it did work (arguably pypy bug, unless proven otherwise) it would still be a slowdown rather than speedup

I'm attaching the patch, which should fix this bug.

[Tres Seaver (tseaver)]

The folks on #pypy say that C extensions under PyPy are always going to be super-slow, because the C extension
compatibility layer is never going to be optimizable.

Therefore, i think we can merge the patch as a "forever" fix for PyPy.

[Tres Seaver (tseaver)]

I plan to merge Arfrever's patch to the trunk for the next release.

I committed a variation on Arfrever's patch in r122115:

  http://svn.zope.org/zope.interface/trunk/?rev=122115&view=rev

Note that several doctests fail under PyPy while passing under CPython,
which is one reason I am not pushing out a quick release.
