Replying to [comment:24 vbraun]:
> This seems to be a known feature of `gcc -march=native` sometimes
emitting SSE4 asm that is not supported by the installed binutils.
I don't think that `gcc` ever checks what the assembler supports. It just
emits instructions and assumes that the assembler knows about them.
