Yeah I don't really understand all the knobs so I copy things from other tests.
I build x86 with -march=native because this gives more vectorization. But this
makes it impossible to whether I need random flag to make things pass when not.
So is there a way for me to run the test in "default" mode without needing to
rebuild the compiler?
