pkgconfig fix - please test

[Marc Matteo <marcm_(_at_)_lectroid_(_dot_)_net>]

Hi all,

Attached is a diff for pkgconfig that basically forces the listing of
"-I/usr/local/include" and/or "-I/usr/X11R6/include" to always appear
LAST when generating a list of cflags (if, of course, they exist in the
first place).

Ideally this will help to avoid header conflicts created when one of
those directories is listed too early.  If you've worked much with a
port that uses pkgconfig you probably know what I mean :).

So look this over and if anyone has any issues with it, let me know.

Marc
