That doesn't help with figuring out what symbols are local to a tool and
which are not. So far the majority of the difficult work could be
off-loaded to the linker. Without -r support, crunchgen would need to
get half a linker built in, which sounds like a bad choice. There are
other users, e.g. FreeBSD uses it for kernel modules on a bunch of
platforms.
