The regex in gnulib checks if @xref is at the beginning

Since we do not use Texinfo and the regex takes almost twice
as much as the rest of our checks, use a custom regex without
the @xref chcecks.

I do not know whether the gnulib regex can be optimized:
bad_xref_re_ ?= (?:[\w,:;] +|(?:see|also)\s+)\@xref\{
bad_pxref_re_ ?= (?:[.!?]|(?:see|also))\s+\@pxref\{
prohibit_undesirable_word_seq_RE_ ?= \
/(?:\bcan\s+not\b|$(bad_xref_re_)|$(bad_pxref_re_))/gims
Either way, we do not need to check for xref in libvirt.

Why don't we drop this very pointless check at all?
