Subject: make 3.79: core dump expanding target specific variables

Consider this makefile:

  t: m+=2

  t:
	@echo "[${m}]"

Then the following sort of works:

  $ make t
  [ 2]
  $

(Interestingly, make 3.77 (which I have kept a copy of) produces a
different result:

  $ make377 t
  [2]
  $

Hmmm.)

BUT the folowing crashes:

  $ make m=hello t
  assertion "current_variable_set_list->next != 0" failed: file "/cygnus/netrel/src/make-3.79.1-2/expand.c", line 489

        0 [sig] make 1580 stackdump: Dumping stack trace to make.exe.stackdump
  Aborted (core dumped)
  $

All is OK with m:=hello on the command line (note the colon), and also
running with make377. None of make-3.79-3, make-3.79.1-1, or make 3.79.1-2
work.
