Well, the "solution" for me was that I managed to install pkg-config on
OS/2 and tinker with the respective .pc files until I got configure to
run through.

But actually, there has to be another way to make the _{CFLAGS,LIBS}
variables consistently uppercased, because ./configure --help lists lots
of other variables that are all uppercase, too (POPPLER_* and FREETYPE_*
for example). I think I understand too little of autoconf to determine
why it works for them but not for png_* and xlib_xrender_*.
