mpv: needs atomics or 8-byte sync

The wscript checks the following.
        'func': check_libs(['atomic'],
            check_statement('stdint.h',
                'int64_t test = 0;'
                'test = __atomic_add_fetch(&test, 1, __ATOMIC_SEQ_CST)')),
and
        'func': check_statement('stdint.h',
                    'int64_t test = 0;'
                    '__typeof__(test) x = ({int a = 1; a;});'
                    'test = __sync_add_and_fetch(&test, 1)'),
It fails if neither of these are available.
