 root at glennmcc-i7:~/build/ffmpeg-6.1.1# time make

 Even tho I disabled pthreads.... it still got these errors and it did not
 build ffmpeg, ffprobe, ffplay for Linux.

Comment:

 ffmpeg has required threading support since
 760ce4bc0bd11f74f0851c0a662dd5cae888df83 (Jul 2022)

 The vulkan make failure looks to be an oversight in the configure script
 but threading is required for vulkan as well.
