I'm not sure why "HOSTCC=gcc-3 make -e" isn't working.  This should 
override the declaration in config.mk.

However, you can always try the alternative (better) syntax:
make HOSTCC=gcc-3

make -e should be avoided because it causes *all* of your environment 
variables to override declarations in the Makefile.  Using the format 
above you can explicity override individual variables.
