Add arch-specific configuration for C11 atomics support.
This sets __HAVE_64B_ATOMICS if provided. It also sets USE_ATOMIC_COMPILER_BUILTINS to true if the existing atomic ops use the __atomic* builtins (aarch64, mips partially) or if this has been tested (x86_64); otherwise, this is set to false so that C11 atomics will be based on the existing atomic operations.
