I'm sure there's an official way to do this.  If nothing else, you can edit 
the global make defaults (probably in /usr/share somewhere?), and redefine CC 
etc. that way.  Otherwise, you can set the CC variable and similar variables 
in the system-wide profile.

I just use a shell script that sets up the variables, then gives me an new 
interactive shell to do compilations etc.

Note that not everything compiles on GCC 4 yet, so even when you get this 
working, it might not be as useful as you expect :(

Also, bear in mind that some of GCC 4's speedier options require special flags 
to be set, since they're not enabled by default.  Problem is, if you enable 
them by default, stuff will probably break :)
