You could instrument ccl with my all new stepper package, trace its
processing while compiling itself, reformat the output to make it even
more "human readable" (or modify my stepper to produce this nicer output
directly).  This would make a procedure that a human could execute to
produce the initial debian ccl binary. 

An alternative would be to have a human just interpret the ccl source
code to compile ccl itself, but it may be too complex, therefore too
error risky.  The first procedure would have more step, but they'd be
simplier steps.

You could write a new target for ccl, that would produce C code instead
of binary code.  Make a cross compilation to that target, and have
debian people compile that C code with the gcc compiler the compiled by
had as described in the first procedure above.  They did that once upon
a time, didn't they?

Because if they never did that, I'm afraid debian may be compromised:

Try to compile gcc 4.5 with gcc 1.0.
