Just to explicitely state the obvious, the problem is that libkvm grown
the dependency on libelf after r291406, and libelf lives in /usr. libkvm
is used before /usr is mounted.

I do not know what is the best way to handle it. Most simple is to move
libelf to /lib. How feasible is to move libkvm to /usr/lib (and all
stuff in / which needs libkvm) is the open question.
