The behaviour I see is that I configure with --cross-prefix=<prefix> 
then the appropriate prefix gets set in config.mak.  However, when 
running "make" the prefix doesn't actually get used.

If building for the same target as the host machine this isn't 
immediately obvious because it uses the host compiler.  However, if you 
run "make V=1" it will show which compiler is being used.
