[Elftoolchain-developers] Overall status from ELF Tool Chain test suite

[Ed M. <em...@fr...>]

I submitted ticket #579 for this issue but I think it's worthwhile
raising it here for discussion. I can't find an easy way to determine
an overall status (pass or fail) from the test suite. For the issue I
just investigated (ticket #575) I bisected the failure by having the
bisect script run "grep 'not ok' test.log" but this is awkward.

Is there an existing way to get a pass/fail from the test suite?
