Luckily this was nothing to do with nolibc -- the build system wasn't
regenerating the initramfs to use the correctly-compiled init, and
things were blowing up because the kernel couldn't find an init process.
With that regenerated it worked as intended.

I'll reply separately for the rest of the nolibc bits shortly.
