ffmpeg @5.x: buildbot failures for 10.9 through 10.11

Description (last modified by mascguy (Christopher Nielsen))

For this new release of FFMpeg, buildbot builds are failing with two different compilation errors.

https://ports.macports.org/port/ffmpeg-devel/builds/

For 10.11, the failure relates to __builtin_available:

libavutil/hwcontext_videotoolbox.c:420:13: error: use of unknown builtin '__builtin_available' [-Wimplicit-function-declaration]
        if (__builtin_available(macOS 10.11, iOS 9, *))
            ^

However, for 10.9 and 10.10, we're seeing the following:

libavcodec/videotoolbox.c:907:13: error: implicit declaration of function 'VTRegisterProfessionalVideoWorkflowVideoDecoders' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
            VTRegisterProfessionalVideoWorkflowVideoDecoders();
            ^

Upstream included the following patch in the 5.0 release, and initially that appeared - at least superficially - like it should fix these issues. But unfortunately that's not the case. (Might be a simple matter of tweaking the preprocessor logic, though.)

FYI for anyone interested: This issue is a blocker, preventing us from updating the non-Devel port to 5.0.

Latest patch gets us further along, but failures still seen for 10.9 through 10.11. More digging needed...
