When $(LINUXINCLUDE) is added to the cflags of a target that
normall doesn't have it (e.g. HOSTCFLAGS), each entry in the
list is expanded so that we search both $(objtree) and $(srctree),
which is a bit silly, as we already know which of the two we
want for each entry in LINUXINCLUDE.

Also, a follow-up patch changes the behavior so we only look in
$(srctree) for manually added include path, and that breaks finding
the generated headers.

This adds an explicit $(objtree) for each tree that we want to
look for generated files.
