> When you are using -march=native then we expect you to have a binutils version that can handle your native ISA.

Note: `-march=native` actually works (just not when used in conjunction with
-O3, -O2 works fine).

Isn't the problem here that GCC 8.1.0 uses the wrong instruction set for
-march=native?
