CMU CL is not designed to be built from scratch. Having SBCL available
as a tool doesn't solve this problem. If you were really determined
you could use SBCL as an *example* (for doing a lot of hacking in CMU
CL) but other than that SBCL isn't going to help.

Was the idea to use CLISP to bootstrap SBCL, then to use SBCL to
bootstrap CMU CL? Are you [Fernando] trying to go from some platform
which only supports CLISP to one which supports CMU CL?

I have not done it, but it should be possible to cross-compile SBCL on
a platform which only supports a C compiler, by doing the Common Lisp
cross-compilation steps on some other platform which does support
Common Lisp. As far as I can see, nothing very tricky is involved,
basically going through the make.sh script, thinking about each step,
and deciding which platform it should be done on and which files need
to be copied between platforms between steps. (And even the "which
files" question could probably be avoided by using brute force, and
simply copying the entire directory between machines between steps.)
