Re: [PATCH] Drop vmlinux dependency from "make install" (take 2)

[i386, x86_64] Remove the dependency vmlinux -> install

This removes the dependency from vmlinux to install, thus avoiding the
current situation where "make install" has a nasty tendency to leave
root-turds in the working directory.

It also updates x86-64 to be in sync with i386.
