An option would be to have a C backend again, and then cross-compile the 
toolchain for the new target, but compile it into C, which then can be 
recompiled into binaries on the target platform.

I actually bootstrapped an SML compiler for FreeBSD/ppc this way a while 
back. A part of the compiler was written in SML and there was an option 
to compile SML to C (that was actually one of the ways to generate final 
code: the C output would then be passed to a system C compiler). I think 
the SML compiler was mlton, but I'm not 100% certain.
