I don't think everything needs to be bootstrapped with an open-source 
compiler.  I have Turbo C++ 1.01 which is a more than adequate C compiler 
for anything I've done with it (ranging from clones of Unix tools to a 
COMMAND.COM to an Apple //e emulator).  Whatever does the job is fine for 

So getting the kernel up and getting files in and out of the image until a 
native C compiler is ready (pcc?) can be done with anything, practically. 
QEMU is a good enough testbed, and gives you well-defined hardware.  Once 
everything is up and running, then maybe one can migrate on to newer 
systems (V7, 2BSD), though V6 should be simple enough as a starting point, 
provided most of it is in C (I haven't really looked).
