1.5.2 broke IRIX module loading

[Randall Hopper]

     I built and tried 1.5.2 this morning, and it failed to load a module
that worked fine on 1.5.1.  See below for the errors.

     This is a C library I don't have source for which has references to a
number of zeroed-out internal symbols which aren't used.  In this case (see
errors), "currstepc" is the exported C interface wrapper, and "currstep" is
the internal FORTRAN routine which has been zeroed-out.

     To convince Python to load this again, I found I had to reverse one of
the 1.5.1 changes to importdl.c (patch attached).  I believe this news post
describes the problem I'm running into:

          http://www.dejanews.com/[ST_rn=ps]/getdoc.xp?AN=289722207

Could we consider reversing this change to importdl.c in the Python dist?
