Ideally, test result diffing tools would be ignoring
" (foo)" at the end test names, because that part is
not considered a part of the test name itself.  It's
extra info.  That's where we write "(timeout)", "(eof)",
etc.  So for instance:

 -PASS: gdb.threads/process-dies-while-detaching.exp: multi-process: continue: killed outside: get integer valueof "mypid"
 +FAIL: gdb.threads/process-dies-while-detaching.exp: multi-process: continue: killed outside: get integer valueof "mypid" (timeout)

... this should be considered a regression, instead of a new FAIL and
a missing PASS.

I think the buildbot diffing script is correctly ignoring that
tail end "(foo)"s.

That said, I think it's still a good idea to make the gdb.sum output
more stable across passing runs, so that plain /usr/bin/diff also
works reasonable well.

Since we can find the number in gdb.log if we need it, this
is fine with me.
