What you grep here are two completely different things. The first telling
the ports to actually use pkg-config (Mk/*), as a port executes it to
gather CFLAGS and LIBS (which you would like to see changed to some
USE_SPECIAL_FOOFOO_TOOL = pkgconfig, if I got that right), the second  
one patching openssl to install it's .pc file into the FreeBSD specific
pkgconfig directory hierarchy (usually /usr/local/libdata/pkgconfig/).
