The flac codec is built with the core optimization level (-O1 on arm).
Earlier testing done on the gigabeast with gcc 4.4.2
showed that compiling the flac codec with -O2 with 4.4.2
was the fastest combination of compiler and optimization level.
So assuming that is true on other arms, we need just a small tweak to
get a flac that's even faster than what we currently have.
