    decay vect tests from run to link for pr95401
    
    When vect.exp finds our configuration disables altivec by default, it
    disables the execution of vectorization tests, assuming the test
    hardware doesn't support it.
    
    Tests become just compile tests, but compile tests won't work
    correctly when additional sources are named, e.g. pr95401.cc, because
    GCC refuses to compile multiple files into the same asm output.
    
    With this patch, the default for when execution is not possible
    becomes link.
    
    
    for  gcc/testsuite/ChangeLog
    
            * lib/target-supports.exp (check_vect_support_and_set_flags):
            Decay to link rather than compile.
