compilers: Debug optimization level should be -O0 (#509)
Without any -O options, gcc does not generate properly debuggable code.
> With no -O option at all, some compiler passes that collect information useful
> for debugging do not run at all
gcc recommends -Og, but that isn't supported by clang, so we use -O0
See https://github.com/mesonbuild/meson/pull/509 for more discussion
