    db: disable the ARM assembler mutex code
    
    The swpb in macro MUTEX_SET will cause "undefined instruction" error
    on the new arm arches which don't support this assembly instruction
    any more. If use ldrex/strex to replace swpb, the old arm arches don't
    support them. So to avoid this issue, just disable the ARM assembler
    mutex code, and use the default pthreads mutex.
