Makefile: Update and remove comments

-  We don't use %/. for directories anymore.

-  %/ targets are obviously directories; no need to say.

-  Don't need to document how we create directories.  That should be
   obvious from the code.

Fixes: ac288b42c ("*.mk: Remove unnecessary '.' after directory names (but keep the '/')")
