Log Message:
Do a better job of duplicate suppression in .MAKEOVERRIDES.
From Var_Set: We actually want the equivalent of
.MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val'
clearing the previous value for name is important, since
doing simple duplicate suppression does not handle:
$ make FOO=goo
which then runs a sub-make with FOO=boo
the commands from that sub-make should see just FOO=boo.
