Norman Feske 6326774056 mk: trigger CUSTOM_TARGET_DEPS from 'all' rule
Build description files that feature both an actual target and
CUSTOM_TARGET_DEPS happen to re-link the target each time whenever one
of the CUSTOM_TARGET_DEPS is phony, e.g., gems/src/app/menu_view/.
The re-linking of the actual target is of course not desired. By
triggering the creation of CUSTOM_TARGET_DEPS from 'all:' instead of
'$(TARGET)', the specified files do not implicitly become link
dependencies of the target.

templates for different directory roles.

:'global.mk': This file contains global variables, for example the
  definitions of the tools to use.

:'generic.mk': Generic rules for creating file types from others.

:'prg.mk': This file represents the target binary role of a directory.
  It must be included by all makefiles that build programs.

:'lib.mk': This file represents a library role. It is never used from
  within the 'src/' directory but only from the <libname>.mk files
  in 'lib/mk/'.
