hush/Makefile
Rob Landley ef8f423e90 Erik pointed out that in the last try at the #ifdef cleanup 
infrastructure, the compiler isn't smart enough to replace const static 
int with the constant, and allocates space for each set of them, 
bloating the executable something fierce.  Oops.

So now, we #define ENABLE_XXX to 0 or 1 for each CONFIG_XXX (which
is still there so the 1000+ #ifdef/#ifndef tests don't have to be
replaced wholesale).  Changed the test instance in networking/ifconfig.c 
to use this.
