    [testsuite] [analyzer] include sys/select.h if available
    
    Test that calls select fails on vxworks because select is only
    declared in sys/select.h.  Include that header if it's present.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/analyzer/fd-glibc-byte-stream-connection-server.c:
            Include sys/select.h if present.
