I think the Debian boot-floppies package does something similar to good
effect, working from a PIC libc.a. Of course, it also helps a lot to have
an integrated swiss-army-knife type of program that does nearly everything
needed, all in one program, all fancy options deleted. I _think_ Bruce
Perens wrote both, but don't quote me on that.

If you're interested, look at or, the sources should not be hard to find. Or ask me
and I'll try to dig it up :-)
