Add arch-specific configuration for C11 atomics support.

Browse Source 
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.

/* SH kernel has implemented a gUSA ("g" User Space Atomicity) support
for the user space atomicity. The atomicity macros use this scheme.
