Comment (by simonmar):

 We might not be able to use the gcc from the stage 0 compiler (I can go
 into details about the particular setup that leads to this problem, but
 it's long and boring).  The point is, if you want to override
 `$(CC_STAGE0)`, there's currently no good way to do it. I think having
 `--with-gcc` set `$(CC_STAGE0)` is fairly sensible provided we're not
 cross-compiling.  I'm open to other suggestions though.
