Without this patch, python detects and uses epoll which only exists in
OmniOS for lx zones and Linux compatibility. It is not quite the same as
the Linux implementation and can cause socket related failures in python.

There is no nice way to tell configure that we don't have it
(pkgsrc get around this by installing a broken epoll.h into the build
 chroot area).
