Now that we are adding our own target we can compile our own toolchain
instead of using the stock one. This does mean that there isn't really a
purpose to using the alpine cc65 image though
Eventually I want the kernel to be loaded from the SD card as well, but
it still needs to separate from user programs.
At some point there should be a folder just for the BIOS, which should
read from the boot block of the SD card and start executing, and thats
it.
