I've just sent the new patch, it's called

tools/build: create two new variables called APPEND_ and PREPEND_ to
add compile flags at the beginning or at the end of the search path

Please take a look at that one if possible. I've left EXTRA_LIB and
EXTRA_INCLUDES as they where, so the new patch should be harmless for
people still using those, while adding the new PREPEND_ and APPEND_
variables.

Thanks, Roger.
