Makefile: Change optimization level back to O3. (#10)

Revert a change from commit cd2a05a
that reverted the optimization level from O3 to O0, which causes
build issues since FORTIFY_SOURCE requires optimization.

Since issues like this only seem to get caught on non-Debian
platforms, add a non-Debian build for comprehensiveness,
so issues like this can be caught before affecting other projects.
