I've took a look at how EXTRA_LIB and EXTRA_INCLUDES are handled, and
found that they are appended to CFLAGS and LDFLAGS, so it's mostly the
same using CFLAGS or EXTRA_INCLUDES. The best way I've come up to
solve this is to modify each makefile and append EXTRA_LIB and
EXTRA_INCLUDES at the end, but this means modifying a lot of
makefiles. What do you think?

Regards, Roger.
