Log:
  Explicitly enable .MAKE.ALWAYS_PASS_JOB_QUEUE for bmake.
  
  This is a NOP as r254419 enabled this by default in bmake.  Add it here though
  to ensure it is known that we are using this as a default and in case a
  bmake import removes the default we have.
  
  This tells bmake to always pass job tokens into sub-commands.  Otherwise
  it would only do so if the target being built depended on the special
  .MAKE target (which causes _all_ commands to be executed with -n as well)
  or if the command matches '${MAKE}/${.MAKE}/$(MAKE)/$(.MAKE)/make' (before
  expansion, so ${LIB32WMAKE} would not qualify).  Using '+' on a command
  (which runs the command with -n) would not pass the job token even though it
  is a documented way to achieve the .MAKE effect on a command.
