Compiling without optimization produces a warning

I work on Chromium, and in my debug build, I always get this warning: src/src/opus_decoder.c:37:10: warning: You appear to be compiling without optimization, if so opus will be very slow. [-W#pragma-messages]

pragma message "You appear to be compiling without optimization, if so opus will be very slow."

     ^

I personally want my build output to be clean, and I'm perfectly aware when doing a debug build that it's debug and might be slow. So I would prefer if this warning was not there.

If it's not acceptable to simply remove this warning, it seems like it ought to be possible to turn this off with a precompile define so that embedders like Chromium can turn it off. We have a large code base and noise in our build output can be very annoying.

I'm willing to do the patch if there's an acceptable solution to this.
