Fixed x86_64 kernel compilation.

For now I've just put all the stub functions that are needed to link the kernel into a file called stubs.cpp. I've not yet moved across the interrupt handling code or the ELF64 relocation code to the x86 directory. Once those have been moved I can get rid of the x86_64 headers/source directories.
