build: fix toplevel check target

Partially revert changes to verbose logging that break the 'check' target
dependencies and trigger many runtime warnings like:
  /home/kodidev/openwrt-project/include/toplevel.mk:213: *** mixed implicit and normal rules: deprecated syntax

Fixes: e4a43cda0 ("build: allow var.% targets to bypass the prepare steps")
