    jobserver: fix fifo mode by opening pipe in proper mode
    
    The current jobserver_info relies on non-blocking FDs,
    thus one the pipe in such mode.
    
    gcc/ChangeLog:
    
            * opts-common.cc (jobserver_info::connect): Open fifo
            in non-blocking mode.
    
    (cherry picked from commit 3f1c2f89f6b8b8d23a9072f8549b0a2c1de06b03)
