[CMake] Prepend compiler flags, fix Clang compiler warnings
Because of issue https://github.com/xiph/flac/issues/437 compiler
flags are prepended instead of appended, so the user can override
them without altering the CMakeLists.txt.
Also, Clang doesn't support per-function optimize options, so in
CMake the fma file gets that option per-file. This is not supported
by automake.
