Revert "Merge branch 'ark-make-help' into 'os-build'"

This change to extend make help needs to be reverted because it breaks make targets (although not the dist-* targets consistently) because it's using mixed colon rules (help: and help::).

Calling make or make mrproper, for example, will result in:
makefile:12: *** target file 'help' has both : and :: entries. Stop.
