Subject: [PATCH 1/2] kbuild: remove misleading stale FIXME comment

This comment was added by commit ("kbuild: Restore build nr, improve
vmlinux link") [1].

It was talking about if_changed_rule at that time. Now, it is unclear
what to fix.

Subject: [PATCH 2/2] kbuild: remove {CLEAN,MRPROPER,DISTCLEAN}_DIRS

Merge {CLEAN,MRPROPER,DISTCLEAN}_DIRS into {CLEAN,MRPROPER,DISTCLEAN}_FILES
because the difference is just the -r option passed to the 'rm' command.

Do likewise as commit 1634f2bfdb84 ("kbuild: remove clean-dirs syntax").
