There's already a $(SED) hack for gdlib-config.in and almost does the
right thing, it's missing -lgd :

$ usr/i686-pc-mingw32/bin/gdlib-config --cflags --libs
-I/Users/tonytheodore/dev/mingw-cross-env/usr/i686-pc-mingw32/include -DNONDLL
-ljpeg -lfreetype -lpng -lz
-L/Users/tonytheodore/dev/mingw-cross-env/usr/i686-pc-mingw32/lib
-lxml2 -lz -liconv -lws2_32

I've attached a simple test program that I modified from one of the
examples. Oddly the test program builds and runs correctly with just
-lgd -lpng -lz specified. It doesn't seem to need -DNONDLL.

P.S. The attached also includes the previous changes for libpng14
