Kbuild: always prefix objtree in LINUXINCLUDE
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. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Michal Marek <mmarek@suse.com>
