This has been fixed in r64639. We now:

  - Warn when a builtin is redeclared with an incompatible signature
  - Error when a builtin is defined (if used as a hosted implementation)
  - Suppress the generation of builtins when the option -ffreestanding is

I assume that the Linux kernel is building with -ffreestanding?
