Weird, but OK.  I really, really think you want to be using := (simple)
assignment here, though, not = (recursive) assignment.

It could possibly even contain more than one.

I really don't know what you mean by "paste its value" and "require some
kind of file write operation".  Are you trying to create a new makefile,
or change an existing one, by adding that value to it in some way?  Why
not just use the variable?
