Hopefully, Andrew will look at this better than I can but what I see:

Looking at the simplest of "cin5_disable_david.log", it looks like you got past the dav1d error by disabling and now have a libvpx error. Disabling parts is not a solution but at least it helps to determine if there is a similar problem in compiling other routines. The error you see below is a compiling error (I think) which is hard to believe that libvpx could have an unbalanced parenthesis or it would not work on other computers.

/tmp/ccmCkgcu.s: Assembler messages:
/tmp/ccmCkgcu.s:1813: Error: unbalanced parenthesis in operand 1.
make[4]: *** [Makefile:160: vp9/encoder/vp9_temporal_filter.c.o] Errore 1

I will see if I can install Arch on a computer here and try it too, but I have never done this before.

I tried a downgrade to nasm 5.14 but it still produces errors. nasm
5.13 is too old and Arch no longer has it in the archive. However, the
month-end build was working fine; it must be an Arch update from the
last week.
I tried disable-dav1d; disable dav1d + libaom + opus; and finally
clang + disable-dav1d. In all 3 cases I get errors. I attach the logs.
