Subject: use %.subdir-{all,clean} targets in root makefile
X-Git-Url: https://git.owens.tech///git?a=commitdiff_plain;h=342b2585b6f93fffce51045fe382d59aa9c382a7;p=vimb.git

use %.subdir-{all,clean} targets in root makefile

- improves consistency: this mechanism is used in other places as well
- fixes dependency tracking: root makefile does not check files directly
  but delegates the task to sub makefiles
