For a cross gcc to produce useful applications, it needs its helper
functions built for the target microprocesor.  Ergo, it needs to
cross-compile and cross-assemble bits of itself at some phase in the
compiler setup process.  This is why you have to build a
cross assembler before you can build the cross compiler.

Theoretically, no compiler *needs* anything target-specific in order
to simply translate C code into ASM code.  But there's more than that
involved in building complete applications--- the anticipated use for
gcc--- so the gcc build process may not be suitable for building a
theoretical, pure C-to-ASM translator, since few people would want
such a thing in practice.

It's entirely likely that various intermediate targets in the gcc
Makefile will yield a "theoretical" compiler.  Use The Source.  :^)


Just my $0.02.
