Updating to a new build root....

Yes, this is necessary (sadly). GCC 4.1.2 and Binutils 2.17 is fairly old at this point, and isn't safe to build KDE 4 against from what I've found due to linking and visibility bugs. At this point, I'm documenting my work in a script to allow future build roots to be built far faster for the update and security trees that will be following.
