C-SKY: Define HAVE_sync_compare_and_swap*.
The SYNC operations are implemented as library functions, not
NSN patterns. As a result, the HAVE defines for the patterns are
not defined. We need to define them to generate the corresponding
__GCC_HAVE_SYNC_COMPARE_AND_SWAP_* and __GCC_ATOMIC_*_LOCK_FREE
defines.
gcc/
* config/csky/csky-linux-elf.h (HAVE_sync_compare_and_swapqi):
Defined.
(HAVE_sync_compare_and_swaphi): Likewise.
(HAVE_sync_compare_and_swapsi): Likewise.
