tools/ lacks a separation into "kernel hacker's testing+debugging
toolbox" and "userspace tools".  It lacks proper buildsystem integration
for the userspace tools, there is no "make tools" and also no "make
tools_install".  Silently dropping new stuff into tools/ and expecting
the world magically noticing isn't going to work.
