    cond test: Don't make assumptions about struct sigaction member order
    
    On x86 (and apparently most other Linux architectures), the union
    with the signal handler is the first member, but on MIPS Linux,
    the first struct member is sa_flags (possibly done to be compatible
    with IRIX). Zero out the struct and fill in the field we want by name.
