We don't support users switching the /usr/bin/gcc symlink, largely
because supporting this would make package builds unpredictable. Just
use gcc-4.4 or gcc-4.5 explicitly instead; most build systems support
doing something like './configure CC=gcc-4.4' or 'make CC=gcc-4.4', and
if they don't it's easy to add.
