library of make fragments

Hi,

I was wondering about the possibility of adding, as a feature to make,
the addition of a standard makefile fragments library. I have started
such a library. It started out as a collection of boilerplate snippets
that I kept privately and copy-pasted into project makefiles. Then I
started breaking them out into includable makefile fragments to make
maintaining them across multiple projects more manageable. I then
realized that they could be generalized and distributed for use by
other people. I have some ideas about adding semantic versioning to
make the API stable, not yet implemented, but here is what I have so
far:

It would be really cool if Make provided something like this in a
manner similar to the relationship between GCC and libc. I'm not a fan
of the implicit rules of Make, and would rather see that kind of
functionality be handled by something like this.
