    testsuite: vect: adjust vect-early-break_137-pr121190
    
    The test needs to require sysconf for _SC_PAGESIZE, and it shouldn't
    override the vect.exp-set vect-enabling options by using dg-options.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/vect/vect-early-break_137-pr121190.c: Require sysconf.
            Don't override vect.exp options.
