Yes, this is how CLISP's compiler was bootstrapped in 1989. I used a
Sun with 8 MB and KCL to compile the compiler, because the interpreted
compiler wouldn't fit in the 1 MB Atari ST. Since then, cross compiling
support has occasionnally been useful when doing incompatible changes
to the bytecode.

You need to go through this full sequence only if the bytecode has changed.
It hasn't changed since 1996-07-19, and is platform independent since then.
You can therefore just take the .fas files from a Sun or other platforms
and use them on Amiga. Afterwards, you should still recompile everything
once, to get the correct code for the few #+/#- conditionals.
