[Bug runtime/6400] New: New runtime unwinder code does not make use of locally built elfutils

[wcohen at redhat dot com]

When attempting to build a snapshot of systemtap checked out of git April 14 on
rhel5 machine, the build failed. It appears that the new unwind code assumes
that the elfutils are installed in the machine and does not make use of the
locally built copy of elfutils. Got the following output when attempting to
build on RHEL5 x868_64 machine:
