Re: dynamically building (temp) include file - how to delete on exit?

The only processing `make' does on the result
is to convert each newline (or carriage-return / newline pair) to a
single space.  If there is a trailing (carriage-return and) newline it
will simply be removed.

So it looks like, that you can not change this behaviour. Workaround
depends on what your script actually does. For example suggested below
you can do something like this

vars_to_define=foo bam
foo_script=echo 123
bam_script=echo hi

$(foreach v,$(vars_to_define),$(eval $(v)=$(shell $($(v)_script))))

.PHONEY: bar
bar:
        @echo foo: $(foo)
        @echo
        @echo bam: $(bam)
