This is literally just +1 LOC for Clang b/c it has a system for adding
no-op flags already, which is mostly used for GCC compatibility.
It even uses it in cases that are quite dubious like making -fstack-
check into a no-op, despite it not just being an optional optimization /
code generation change like -fno-plt.
