Yes, I agree this is better for many cases, but not for all. Implementing
RNG that is good enough for the tests' purposes, fast enough not to steal
the benchmarks' hot spots and does not use target/library-specific code is
not trivial. I think that, in this particular case, having bugs in GCC is
far less problematic than assuming fixed outputs.

I've tried USE_REFERENCE_OUTPUT := 0 on the Makefile, but the test.log
still prints it as 1 (and fails).
