configure: detect redundant --with-libpcre & --with-libpcre1
The --with-libpcre option is a synonym for the --with-libpcre1 flag, but the configure script allowed for redundantly specifying both. Nothing broke as a result of this, but it's confusing, so let's disallow it. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
