We don't actually know anything about the binary format so failing
to parse ELF cannot assume anything.  That's why it falls back to
the symlink checks and such.

Ideally we should detect linker scripts and always use full paths
to them to make sure the proper script is used, and then trust it
to know what it is doing.
