[arch-dev-public] GCC update in core and kernels

I noticed GCC has been moved to the core repository today. AFAIK, modules built with GCC 4.3.1 won't load in a kernel compiled with GCC 4.3.0 and the other way around. If this really is the case, we should rebuild the kernel and all modules with the new GCC and while we're at it, close some bugreports that require a rebuild of the kernel and all modules also.
