   5 # MakeInc.dir contains the recursion rules for the build system.
   6 # For instance, the "build_installhdrs_md" target is auto-generated
   7 # such that make(1) recurses into a specified set of subdirectories
   8 # (building "build_installhdrs_md" in turn at each level) before
   9 # building the special "do_installhdrs_md" target at the current
  10 # level. "do_installhdrs_md" is defined in MakeInc.rule.
  11 #
  12
  13 # $(1) is the name of the target to produce that will perform the
  14 #      recursive behavior via dependencies
  15 # $(2) is a list of subdirectories to recurse into
  16 # $(3) is the target to build with a sub-make after
  17 #      the subdirectories have been recursed into
  18 # $(4) should be "1" if TARGET should be pinned to the per-arch
  19 #      build COMPONENT directory, or empty if it should recurse
  20 #      in lockstep with the source recursion
