Several architectures discards .exit.text in the final linker
script (arch/$(ARCH)/kernel/

So any references to .exit.text will when a module is build-in result
in a linker error because ld will flag it as an error when we reference
a symbol in a discarded section.

For the popular architectures (i386,x86_64) we discard .exit.text at
runtime so here we do not see the error from ld (sadly).
