Ahh it makes sense, the same thing happens with a remote target (the same procedures
in Dejagnu are used to upload the files). So there could also be some clash when
testing with a remote target, if there are two tests with the same name, or tests that
use the same external files/libraries. That's why I found that odd, why a remote host
in particular is dangerous, and not a remote target.
Otherwise, the README LGTM.
