While the change in glibc is most certainly correct (I don't have enough background knowledge to comment on that), it broke qemu-user for everyone and so far there is no possible fix in sight. I am CC'ing this to libc-alpha in the hope that someone from glibc upstream might give us a tip on how to resolve the issue. Not being able to use qemu-user anymore is quite a deal breaker because lots of people use qemu-user for debugging issues on foreign architectures which is now no longer possible.
