Before commit e28cbf22933d0c0ccaf3c4c27a1a263b41f73859 64-bit x86 had
a private implementation of sys_uname which was just called sys_uname,
which other architectures used for the old uname. Due to some merge
issues with the uname refactoring patches we ended up calling the
old uname version for both the old and new system call slots, which
lead to the domainname filed never be set which caused failures with
libnss_nis.

Yes, that's the same patch I arrived at and fixes the issue for me.
