Try this:

   make tools/help

and then actually *LOOK* at what it prints out.

Notice how it says 'nolibc' is a target here.

And then think about it. Just for fun, try doing

   make -C tools/ nolibc
   make -C tools/ nolibc_install

like that help message implies you should do.

Does it work? No.

Put another way: where did you find that "nolibc_headers"?

THAT is what I'm talking about. You are mentioning all these magical
things that don't match the documentation you yourself added.
