Only if they are _very_ interested, and have the knowledge/talent to
do that.

OK, let me rephrase: we should choose our JIT library so that it
suffers as little as possible from such issues.

I don't think this is the idea.  I think the idea is to strive to
support as many popular platforms as we can.

That again needs a compiler and Binutils, so it suffers from the same
drawback.
