[opus] opus_multistream_encode_float not working in libopus 1.1

Whoops, looks like I replied directly instead of to this list.  Sorry
'bout that.

I did some experimentation this morning and I discovered that it seems
to only fail when I try to encode with Hard CBR;
opus_multistream_encoder_ctl(st,OPUS_SET_VBR(0));

Not since the last time I tried to compile it, when I got so many
dependency errors that it made my head spin clean off.  Have not
attempted to compile since then.  However, even if I could compile
them, I'd still prefer to code, test, and use the ones already
compiled, that way people can find them online and swap out different
versions if they wanted to.
