[J-core] Is a small Linux distribution available for J2 on Numato Mimas?

[Brian Bartholomew]

Has anyone compiled a small Linux distribution for J2 on the Numato
Mimas?  By "small" I mean has emacs and can build packages natively,
but doesn't have X-Windows.

I've read several presentations on cross compilation which I found
around Aboriginal linux, which said to run the make and configure on
the target in qemu.  This is a big improvement over the last time I
cross compiled a Linux distribution, which used distcc but ran the
configure on Intel.  I'd rather not set all this up for myself yet, if
someone has already done it and J3 is coming soon.

Thanks,
Brian
