Fix compiling bundled Kerberos library on several 32-bit architectures by linking with libatomic.

Disable kernel keyring being picked up from a dirty buildbot environment.

Remove libpthread dependency since it's integrated into libc.

Lexicographically sort configuration arguments and dependencies.
