If you use a makefile with only that rule and then invoke `make'
then effectivly you are explicitly trying to make Makefile.
From what I understand from reading the docs at gnu.org/manual
is that if I provide a rule to update a makefile (a makefile that
is /used/) then it should be updated before any other targets.
To test this rule without my entire build environment,
I used a makefile like this:
####################################################
all:
@echo "Thats all she wrote"
$(CURDIR)/Makefile:$(CURDIR)/globalconfig/Makefile
@echo -n "Updating address@hidden "
@cp -f $< $@
@echo "Done."
# XXX This line fixes it, but I don't think I should need it
#all:$(CURDIR)/Makefile
####################################################
