if we want to track down regression test some day or the other, we
need to have a reference hash.
IMHO, we need to commit one and let the person who runs the regression
tests use the relevant version. Maybe we can refine later on, but
surely having no way to check regression isn't a good idea!

Now, maybe there are other problems such as: mmx, altivec, etc...
implementations have different rounding and therefore different hash,
which also isn't gonna make things easy.... well...
