Yes, that's fine. The MXE build system sets that up correctly. It's only 
important for external build.

Are you adding too much to the path? You must only add 
"/mxe_dir/usr/bin". *Not* "/mxe_dir/usr/$TARGET/bin". This will break stuff.

If you get different output compared to native pkg-config, it works. For 
example, on Linux, vorbis is missing "-lm" in --libs.

That's normal. It seems the default library path is never printed.

Does that work? If yes, then you could edit the mk and use 
"--disable-static --enable-shared". Then search for the dll in usr/.
