It fixes symbol clashes between libc and kernel names by redefining
the kernel name in any file that is built against kernel headers.

This fix is fairly nasty, but simple and it works.  My long-range plan
was to build all of the kernel objects into a single self-contained
object with no dangling references and link it into the userspace
stuff, but I never acquired the ld-fu to pull that off.
