That uses glibc 2.11, and the (rather lengthy) conftest.c test for GNU
getopt has a piece that is commented as "This code fails on glibc 2.11".
Although it never gets a chance to return 32 since it apparently also
triggers the "core dump" section and so returns 1.

It also dumps core on RHEL6 with glib 2.12. So apparently you need to be
bleeding edge to have a GNU getopt good enough for gnulib... ;)

Me neither.

This is a dupe of http://debbugs.gnu.org/10108, BTW.
