According to <URL:https://stackoverflow.com/questions/27290086/gcc-canaries-undefined-reference-to-stack-chk-guard > these are related to the stack protector option for gcc. I guess either you need to turn off that option, or define the two requested global symbols.

Yes, disable it is ok.

Yes, disable it is ok. What commands did you run to disable it?

https://github.com/xiph/opus/commit/b83dd52868326a401c8578041e3dbea439d53f11 should have fixed this.
