+1

It is wrong to not compile a kernel or bootloader with -ffreestanding
(and -ffreestanding implying -fno-builtin is *also* correct; kernels
and bootloaders can use stuff like __builtin_strlen explicitly if/when
desired *and* aware of the side effects).

FWIW, adding -ffreestanding to the kernel I inherited from OpenBSD
fixed several issues at once…
