I'm not so sure: When we examine kernel probes, we're able to consider
different paths for local vs. cross-compiled kernels.  But when trying
to probe "/usr/bin/foo", we're only considering what's local.

Perhaps we need a "--rootfs" option? This could give a local path to
find binaries that will be located on the root of the target.  i.e. for
translation we'd look at "$rootfs/usr/bin/foo", but at runtime
task-finder would match simply "/usr/bin/foo".
