Subject[PATCH v1] kbuild: Use '-f' instead of '--file=' for grep
From
The posix grep utility doesn't support the longer '--file=pattern_file'
command line option which was introduced in commit ce697ccee1a8
("kbuild: remove head-y syntax"). Let's update Makefile to use '-f
pattern_file' to fix the compiling error:

grep: Unknown option 'file=.../scripts/head-object-list.txt'
(see "grep --help")
