In this case I only have the flag because I want the bootstrapping with gcc to 
be

(1) similar to the mescc-compiled version
(2) reduced complexity - no two different frame pointers, two different 
instruction decoders, two different branch offset calculations (!) etc

So hard-coding CFLAGS=-marm would be fine.

Maybe even hard-coding CC="gcc -marm" would work and be more paranoid.  Not 
sure...

A bootstrapper really shouldn't inherit a bunch of things from the environment, 
so CFLAGS not being overridable is fine here.
