Isn't "make bootstrap" usually used for building native compilers?

For building a cross compiler for PowerPC (and others), I use the script I 
posted in this message:

    http://sources.redhat.com/ml/crossgcc/2004-08/msg00173.html

That post didn't include the PowerPC patches I use to allow building programs
with the "-mmvme" option.  Those are attached here.
