fijal on IRC helped me to get set up, but it looks like my board won't
be helpful -- it's armv5tel, and the ARM backend wants armv7l.  Running
test_all gives:

[cjb at koji3 pypy]$ python ./pypy/test_all.py pypy/jit/backend/arm -x
========================== test session starts ===========================

pypy/jit/backend/arm/test/test_assembler.py .Illegal instruction

So, unless it's easy and worthwhile to add armv5tel support to the ARM
backend, I'll give up for now and let you know if I find any large-RAM
ARMv7 boards in the future.
