I suspect that either clang for cross-build is misconfigured for armv6, or universe uses wrong clang (again, for armv6, instead of for arm). I.e. there are two issues to fix, one is wrong native (or cross) clang, and another is the use of the mrrc instruction on ARM v5 in libc (but the code should not be executed, it is only compiled). For later, see how I encoded isb in the same file.
