#3599 gcc-torture-execute-?sad-run.c fail for -ms08 --stack-auto

[Philipp Klaus Krause]

The regression tests gcc-torture-execute-ssad-run.c and gcc-torture-execute-usad-run.c fail for test-s08-stack-auto when enabled in support/regression/MakeList.(for now the test-s08-stack-auto target is only in the next branch, after 4.3.0 in trunk).
