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

Binutils increase the size of initramfs by 36 MB. 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.
