configure.ac : Erase default -O2 when setting -O3.
Previously CFLAGS had a -O3 at the start and a -O2 at the end. According
to the GCC docs:
https://gcc.gnu.org/onlinedocs/gcc-4.9.1/gcc/Optimize-Options.html
"If you use multiple -O options, with or without level numbers,
the last such option is the one that is effective" which means that
GCC doesn't try to use SIMD to vectorize the code, etc."
