FWIW, I checked in a patch to check for srandom()
and disable (by returning POPT_ERROR_BADOPERATION) if
HAVE_SRANDOM was not defined when popt was built.

I think we both agree that popt not building if
srandom() is not present is a flaw no matter whether
its solved by disabling POPT_ARGFLAG_RANDOM or by adding
gnulib either internally/externally.
