Yes ;-)

The longer answer is that we've just run SPEC, but now have also tried the
full test-suite (via LNT) and there are no new failures when run with:

  --optimize-option=-O0 --small

Existing failures that weren't affected by the change (running on x64
Linux):

FAIL: MultiSource/Applications/ClamAV/clamscan.execution_time (493 of 984)
FAIL: MultiSource/Applications/obsequi/Obsequi.execution_time (494 of 984)
FAIL: MultiSource/Benchmarks/Olden/voronoi/voronoi.execution_time (495 of
984)
