I think we already have an option that is appropriate here, --cross-compiling.
You just need to make it do the above. The only catch I can think of is
that when I reconfigure the source distribution on my build machine, then you
need to make sure that settings like --max-arg-packing-bits end up being
consistent with the pre-generated C files.

That should just be a matter of:
And indeed if you change the grade to hlc.gc you will get a source
distribution whose C files are
high-level C code.
Is it worth having multiple versions of the source distribution or is
it just going to be confusing though?
