Debug info suppot is a nice-to-have when you trace instrumented user
applications. It's not the end of the world, IMO, to build host-elfutils
when you need host-lttng-babeltrace anyway... one of the reasons of
having lttng-babeltrace as a host package in the first place is that
some distributions provide an outdated Babeltrace package, and the
recent Babeltrace 1.4 offers this debug info feature.
