[PATCH 1/2] test-lib: add LIBPCRE1 & LIBPCRE2 prerequisites

From: Ævar Arnfjörð Bjarmason <avarab@gmail.com>
Date: Nov 22, 2017, 13:36 UTC
Message-ID: <20171122133630.18931-1-avarab@gmail.com>

Add LIBPCRE1 and LIBPCRE2 prerequisites which are true when git is compiled with USE_LIBPCRE1=YesPlease or USE_LIBPCRE2=YesPlease, respectively.

The syntax of PCRE1 and PCRE2 isn't the same in all cases (see pcresyntax(3) and pcre2syntax(3)). If test are added that test for those they'll need to be guarded by these new prerequisites.
