undefined reference to `pcre_jit_exec'

[Jeffrey Walton <noloader@xxxxxxxxx>]

Hi Everyone,

I have a script to build Git on some old platforms to ease testing.
Old platforms include CentOS 5. The script is available at
https://github.com/noloader/Build-Scripts/blob/master/build-ssh.sh.

It looks like something got knocked loose recently. I'm seeing several
of these when building with PCRE 8.41 with Git 2.14.2. Old and new
platforms are witnessing it. I observe it on CentOS 5 with GCC 4.1;
and Fedora 26 with GCC 7.2.
