-Subject: [PATCH] configure: use user set pcre-config
-
-Setting a non default configuration script location is common practice when
-cross compiling, since the target library might need different flags. zsh
-configure scripts allows the user to set pcre-config location but doesn't
-actually use it. Fix this.
