   8 # This file is included by all Makefile-templates. This file defines macros
   9 # for div commands, sets general DROPS-Makefile variables, ensures the
  10 # dependencies from the various Makeconf.locals, defines the messages for
  11 # div actions, and permits the dependency-creation on clean-rules.
  12 #
  13 # The macros BUILD_MULTIPLE_ARCHITECTURES and BUILD_ONE_ARCHITECTURE are
  14 # defined here.
  15 #
  16 # BUILD_MULTIPLE_ARCHITECTURES is set if ARCHS is set to multiple
  17 # architectures in the Makefile. If ARCHS is not set, the default value
  18 # l4_i386 will be assumed, not defining BUILD_MULTIPLE_ARCHITECTURES.
  19 # In the muli-arch case, binary.inc triggers build the files into subdirs,
  20 # dir-name is the architecture. Then, make is called recursively with ARCH
  21 # set to one architecture.
  22 #
  23 # BUILD_ONE_ARCHITECTURE is set if ARCH contains one architecture, and we
  24 # actually build files (in subdirs for multi-arch case, in the same dir in
  25 # the single-arch case).
