toolchain: xtensa: Define __sync_synchronize This builtin gcc function is not available in xcc compiler. Adding a memory compiler barrier as it is done in compiler_barrier. compiler_barrier() and __sync_synchronize() are not the same, the former is a sw barrier while the latter can be a hw barrier like (mfence/sfence) in X86. I didn't find anything equivalent for xtensa so just implementing a SW barrier. Signed-off-by: Flavio Ceolin <flavio.ceolin@intel.com>
