tests/test-suite.log build failures

[Xavier Roche <rocheml@httrack.com>]

Hi folks!

I had a build failure (*) on my package due to a failing unit test, and
the only information I got (with the failng unit test) was:

# TOTAL: 12
# PASS:  11
# SKIP:  0
# XFAIL: 0
# FAIL:  1
# XPASS: 0
# ERROR: 0
============================================================================
See tests/test-suite.log

Would it be relevant to emit to stderr the tests/test-suite.log content
in this case to ease debugging (or to keep it somehow) ?

[ I'm currently trying to find a S390x machine where to do tests, but I
suspect a temporary glitch ; restarting this specific might be sufficient ]
