Optionally, add your custom agent binary to the rootfs with the following commands. The default `$LIBC` used
is `musl`, but on ppc64le and s390x, `gnu` should be used. Also, Rust refers to ppc64le as `powerpc64le`:
```
$ export ARCH=$(uname -m)
$ [ ${ARCH} == "ppc64le" ] && export LIBC=gnu || export LIBC=musl
$ [ ${ARCH} == "ppc64le" ] || [ ${ARCH} == "s390x" ] && export LIBC=gnu || export LIBC=musl
$ [ ${ARCH} == "ppc64le" ] && export ARCH=powerpc64le
