Please test the following inlined patch:

Unrelated:
The configure option arch does not do what you think it does,
remove it.
I suggest you remove the optflags: Yours do not look completely
insane (as they usually are) but setting them is still a good way
to break compilation.
Not sure if enable-bzlib has an effect, I recommend to remove
it to make the configure line more readable.
disable-libdav1d looks useless.
enable-vaapi has no effect.
enable-stripping is the default
enable-postproc has no effect
enable-runtime-cpudetect does not do what you think it does,
remove it.
enable-indev=jack has no effect
enable-nonfree is only needed once
enable-avfilter has no effect
