Well, my Makefile(s) are really few, since I'm using the SDK environment (while
there are so many good reasons to avoid it as well).
I had some Makefile created by SDK for my lwip library, and they run from EDK
shell too (though they _always_ recompile all), I can attach them here.
I changed a very few lines of these files, and I guess you'll have to switch all
the mb-gcc, mb-ar, etc. in something like powerpc-eabi-gcc, ecc., plus linking
it all in an executable (my Makefile serves as a library generator)
