Brandon Bergren bdccf0bbac Implement _umtx_op_err.S on powerpc / powerpc64. 
As per r177853, we need to avoid using errno inside user mutex code, since
 signal handlers can interfere with it and mess up libthr internal state.

So, implement _umtx_op_err() instead, which makes a raw syscall and
returns the error value directly instead of using errno.
