[erlang-questions] has anyone cross compiled HiPE?

Answering my own post
> Q1: Has anyone already managed to cross-compile HiPE for ARM?
I got mail from Frank Hunleth confirming that he'd done it. He also
gave me his patches. He plans to submit them to erlang-patches.
It's fairly straightforward, the main wrinkle is that you need to run
'hipe_mkliterals' on the intended architecture. There are a few ways
to do that.
Frank did that by using qemu (a general purpose CPU emulator).
I did it by running hipe_mkliterals on the embedded system and copying
over the results.

For now, I do it by compiling the Erlang modules on the target. This
is slow, e.g. compiling the 'string' module takes 400ms on my PC and
about 40s on the target.
