After some further tests, it seems swscale (used as the auto_scaler in the
test) produces slightly different output depending on whether MMX is enabled or
not.

When I re-add --disable-optimizations --enable-mmx --disable-stripping to my
configure command line, the test succeeds.

Any further comments to the patch and test case?
