With CONFIG_HAVE_ARCH_PREL32_RELOCATIONS=y, the following code fails to
build:
---------------->8----------------
#include <linux/init.h>
int foo(void) { return 0; }
core_initcall(foo);
---------------->8----------------
Include <linux/build_bug.h> for static_assert() and <linux/stringify.h>
for __stringify().
