Subject: kbuild: Ignore glob patterns that don't match any file

It is useful to specify glob patterns in platform files to select device
tree sources. When switching development branches, some patterns may not
match any file. The shell expands those patterns to themselves, which
causes build failures. Fix this by setting the nullglob option, to make
those patterns expand to a null string.
