Question about bmake in parallel mode

[Aleksey Cheusov <cheusov%tut.by@localhost>]

Hi. I'm developing an application with bmake as a build system.
The simplified version of Makefile is below.
The problem in it is that it doesn't work with -jN because
order of build "realdelete" and "/tmp/first" (both they are dependencies
for "delete")
is not specified regardless phony target /tmp/first is a
prerequisite for phony target "delete".

In general I often want to do the following. A target "first" is
a prerequisite for phony target "last" which in turn has a number of
prerequisites, and I want to build "first" before any prerequisite for
"last"
and "last" itself.

In this simple Makefile uncommenting the first .ORDER line solves the
problem.
But in general I have to track all  dependencies for the target "delete"
and use something like
  .ORDER: all_prerequisites_for(delete) realdelete
This is the second commented line in Makefile. It is possible in bmake?

Is there any "cleverer" alternatives?

Manually tracking dependencies for "delete" is a bad solution because
I have no control over other programmer's needs and code.

Any help?

=============================
.PHONY: all delete realdelete

all: delete

delete: /tmp/first

#.ORDER: /tmp/first realdelete
#.ORDER: all_prerequisites_for(delete) realdelete

delete: realdelete

realdelete:
        rm /tmp/first

/tmp/first:
        touch /tmp/first
