Possibly; I don't know.  I don't recommend --with-included-getopt.
You might ask on bug-gnulib.

glibc regex is quite a bit different now.  It has essentially dropped
support for Emacs split buffer.  Therefore, Emacs won't ever want to
use it; it always wants its own regex.h and regex.c.  Perhaps this
should be cleaned up at the gnulib level at some point, but nobody's
had the time to do it.
