    testsuite: Adjust scalar-test-neg-8.c with lp64 [PR108730]
    
    The built-in function scalar_test_neg_qp is under stanza
    ieee128-hw, that is TARGET_FLOAT128_HW.  Since we don't
    have float128 hardware support on 32-bit as follows:
    
    if (TARGET_FLOAT128_HW && !TARGET_64BIT)
      {
        if ((rs6000_isa_flags_explicit & OPTION_MASK_FLOAT128_HW) != 0)
          error ("%qs requires %qs", "%<-mfloat128-hardware%>", "-m64");
        rs6000_isa_flags &= ~OPTION_MASK_FLOAT128_HW;
      }
    
    So adjust the case with lp64 effective target accordingly.

            effective target requirement.
