this sounds like theres a problem in your build system, and IMHO it
should be fixed there. That is either your compiler should not
add calls to sincos or the libs have to provide this function.

Also if this is a problem that does affect more than your box then
you would help many more people if the compiler or lib is fixed than
if a workaround is added to ffmpeg.

Thanks
