Make compilation optimized unless debugging

Note: I wanted to enable `-Og` on `develop`, but this generated warnings
(thus, errors) that aren't in `-O0`. Needs further investigation, but
annoyingly some of those are within `extern/` code, thus requiring
different flags, which AFAIK is only possible (sanely) with GNU Make.
