Many of the test out files are normally empty, but many others are not.
However, I think it's the case that they should all exit abnormally if they
fail, so `make check' should obviously fail if something is wrong, in theory.

The best answer is that you should do a native Linux build of glibc and
compare the `make check' results from that to what you get on the Hurd.
But I can tell you now that if e.g. all the stdio-common/ and libio/
test output files are empty, then there is definitely a bug.

I'm not really following your question here.  When libc runs a program
built against the newly-built libc, the only way it can do that without
installing first is to run the new ld.so directly.

Never hurts.
