[PATCH] UML - Build cleanups

[Jeff Dike <jdike@addtoit.com>]

Uml-specific patch (which requires a mainline hook, mailed separately).

This patch avoid the linking kludge which leaves kbuild link vmlinux and
then link it with libc inside linux. This kludge has the big problem of
making kallsyms break, since the kallsyms pass is done on a completely
different binary than the running one.
