Also, looking into this a bit more, in my case I do see arch/arm64/crypto/.aes-glue-ce.o.cmd containing the command line and the full set of include/config/... rules that are used to track dependencies on the configuration.
So what strikes me as odd is this:
> CC [M] arch/arm64/crypto/aes-glue-ce.o > ld: cannot find arch/arm64/crypto/aes-glue-ce.o: No such file or directory
so it seems make is perfectly happy to create the aes-glue-ce.o file, but the subsequent ld that uses it as input cannot find it. Perhaps the dependencies are screwed up elsewehere?
Are there any other circumstances of interest? How many threads are you building in parallel? Other steps to reproduce?
