 Reproducibility. I tested this for something (I think it was flex, but as usual
I don't remember exactly), and the code generated by my system's flex was wildly
different from what was generated by Buildroot's host-flex, even though the
versions were pretty close. Unfortunately, I don't remember exactly, but that
was my concern.

 Arnout
