Merge PR #5479: BUILD: Fix -Wunused-function when compiling without rnnoise

The clampFloatSample function is only used when rnnoise support is enabled, when it isn't this the presence of the function (since it is static) causes a -Wunused-function warning which ultimately ends up causing a build error due to -Werror.
