Some applications, such as tests/vmm/vmrunkernel.c and perf need
libelf, from elfutils.  We have a port of that library to Akaros.

To build it, the easiest thing is to:

$ make apps-install

from your $AKAROS_ROOT directory (the git repo).

That will also build perf, which is now at tools/dev-util/perf (It used
to be somewhere else).  It will also rebuild bash, busybox, and a
couple other things.

This is a relatively recent change, and was probably not something you
had to do the last time you built the system.
