Always remake target

[Casper Hornstrup]

Hi.

I have a makefile, called makefile, and a tool that builds another makefile 
(okay, it does a little more than that), called
makefile.auto. Makefile ensures that makefile.auto is regenerated using 
dependencies on makefile.auto.

Now I need to always regenerate makefile.auto, but only for specific goals (all 
and empty goal - i.e. default goal).

So in short. If I run "make module1", I want make to only regenerate 
makefile.auto in case one or more of its dependencies are
remade. If I run "make" or "make all", I want to always remake makefile.auto 
before any target that depend on it is remade.

How can this be done?

Pseudo makefile is below:

.PHONY: all
all: makefile.auto module1

-include makefile.auto

makefile.auto: tool
        # regenerate makefile.auto using tool

# The rest is in makefile.auto

.PHONY: module1
module1: module1.exe

module1.exe: $(MODULE1_OBJS)
        # build module1.exe
