There is no file getopt_pfx_core.h in current Gnulib, so it sounds like 
you have some sort of mixture of old and new Gnulib imported into 
libvirt's source directory.  suggest ripping out all the old stuff and 
importing the latest Gnulib version.

To help debug this, you might try getting the latest Gnulib sources and 
running "./gnulib-tool --test getopt" on your rawhide development 
platform. If that command doesn't work, it's probably a Gnulib bug; if 
the command does work, it's probably something else wrong with your setup.
