 Apple broke the poll() call again in Sierra resulting in failures in the
 python test suite at...

 Since the configure in python 2.7.12 doesn't have fine enough control to
 eliminate the usage of the poll() calls, I resorted to...

 {{{
                 perl -pi -e 's|\#define HAVE_POLL 1||' ./pyconfig.h
                 perl -pi -e 's|\#define HAVE_POLL_H 1||g' ./pyconfig.h
                 perl -pi -e 's|\#define HAVE_SYS_POLL_H 1||g' ./pyconfig.h
 }}}

 post-configure which allowed fink's python27 package to successfully pass
 'make check'. MacPorts will need similar hack for the 10.12 python package
 builds.
