In Wheezy, libpcre3 and libpcre3-dev came by virtual of being dependencies of libaprutil1-dev, which in turn is a dependency of apache2-prefork-dev. As of Jessie, libaprutil1-dev no longer requires PCRE.
I note that Evergreen's direct dependency on PCRE is new as of 2.10 (see bug 1468422), so I will remove the 2.8 and 2.9 review targets.
