Modulo (operator%) does not give correct result

[silverscampi]

I noticed in a larger program that I compiled JIT with amacc, which relies on modulo for prng, that the results were wrong. So I made a small test program, and tried a freshly cloned amacc on it - as you can see below the results are completely wrong.

(Here is a hacky fix for now, which requires the use of mod(a, b) instead of a % b - it gives the correct results for the shown small test program)

@lecopzer, can you help verify and resolve EABI specific modulo operation?

OK, I need some time to figure out this issue.
