Hello,

I'm doing the ffmpeg binaries for macOS, but I've noticed something
very strange today after my build:

Several libraries (AVFoundation, CoreVideo, CoreGraphics, QuartzCore,
AudioToolbox, VideoToolbox) are no longer linked (even though
videotoolbox and audiotoolbox are found during configure).

my config.log is here: https://evermeet.cx/pub/tmp/config.log

./ffmpeg:
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version
400.9.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 1252.50.4)
	/System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate
(compatibility version 1.0.0, current version 4.0.0)
	/System/Library/Frameworks/CoreText.framework/Versions/A/CoreText
(compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1454.93.0)
	/System/Library/Frameworks/Security.framework/Versions/A/Security
(compatibility version 1.0.0, current version 58286.70.9)

My last binary 92486-g8f875a90c4 looked like this :

./ffmpeg:
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version
400.9.0)
	/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation
(compatibility version 300.0.0, current version 1454.93.0)

	/System/Library/Frameworks/AVFoundation.framework/Versions/A/AVFoundation (compatibility version 1.0.0, current version 2.0.0)
	/System/Library/Frameworks/CoreVideo.framework/Versions/A/CoreVideo

	/System/Library/Frameworks/CoreGraphics.framework/Versions/A/CoreGraphics (compatibility version 64.0.0, current version 1161.21.0)
	/System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL
(compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate
(compatibility version 1.0.0, current version 4.0.0)
	/System/Library/Frameworks/QuartzCore.framework/Versions/A/QuartzCore
(compatibility version 1.0.1, current version 5.0.0)
	/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit
(compatibility version 45.0.0, current version 1561.60.100)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1454.93.0)
	/System/Library/Frameworks/Security.framework/Versions/A/Security
(compatibility version 1.0.0, current version 58286.70.9)
	/System/Library/Frameworks/AudioToolbox.framework/Versions/A/AudioToolbox (compatibility version 1.0.0, current version 492.0.0)
	/System/Library/Frameworks/VideoToolbox.framework/Versions/A/VideoToolbox (compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices (compatibility version 1.0.0, current version 822.37.0)
	/System/Library/Frameworks/CoreText.framework/Versions/A/CoreText
(compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current
version 228.0.0)

I'm really puzzled as to why this is happening. Did someone change the
configure script?
Also, all of a sudden /usr/lib/libobjc is no longer linked either.

Cheers,
  K. C.
