Hmm, not sure what's going on.

__ctzdi2 should be in a (linux/s390) header somewhere. I am pretty sure its timezone related. I cant see anything Musl related but there was this (note not exactly the same):

It implies its possible its GCC (the glibc?). What was that other error you got on aarch64 which forced you to change it back to using GCC 9.2?
