Bump compiler version.
We have to remove the `#[naked]` attribute from `_start` for now, since it emits
a warning now when used with non-asm statements in the function body. For now,
just hope for the compiler's mercy to not emit code using the stack pointer
before we've actually set up a stack.

RPi3. Switch to using the correct way.

Also, configure pull-ups for both UART pins.
