Where did the -O optim flag go?

It seems that since the introduction of the -march=native flag, the -O2 or -O0 flags are no longer given to the compiler, resulting in an embarrasing slow-down.

The "-O" flags is set by SET_FLAGS in configure.ac. But the call to this macro was remove in commit f1f9ee7 (the last commit that modified configure.ac). I make a PR reverting this commit for this file.
