avcodec/videotoolbox: Fix undefined symbol with minimal configuration
Please reproduced with the following minimal configure command:
./configure --enable-shared --disable-all --enable-avcodec
--enable-decoder=h264 --enable-hwaccel=h264_videotoolbox
You'll get below error:
Undefined symbols for architecture x86_64:
"_ff_videotoolbox_vpcc_extradata_create", referenced from:
_videotoolbox_start in videotoolbox.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
