gcc-3.x requirement and DragonFly

[Hasso Tepper <hasso%estpak.ee@localhost>]

There are some notable packages which have problems compiling with 
gcc-4.x, but compile and work fine with gcc-3.x. audio/festival and 
emulators/qemu are such examples.

DragonFly has two compilers in the base. Default is gcc-4.1.2, but 
gcc-3.4.6 is there as well. Compilers are switchable with environment 
variable CCVER:

$ gcc -v 2>&1 | grep version
gcc version 4.1.2 (DragonFly)
$ export CCVER=gcc34
$ gcc -v 2>&1 | grep version
gcc version 3.4.6 [DragonFly] (propolice, visibility)
$

The problem is that I have no idea how to support it in pkgsrc. Of course 
I can do whatever locally, but I'd like to get pbulk builds to work as 
well, so this switch should be automatic. Any ideas, pointers etc?
