Subject: [PATCH] Make binutils optional when elfutils are available

This is intended for minimum host OSes where 36 MB used by binutils
are deemed too expensive. We only need "strip", which exists as eu-strip
in elfutils, which in turn is < 1 MB in size.

Note that the tests (TEST-04-FULL-SYSTEMD/test.sh) still depend on
strip from binutils. It could use sstrip in the future.
