    ppc: testsuite: require target effectively [PR104253]
    
    The testcase was missing dg- before require-effective-target.
    
    While at that, I'm also pruning the excess-error warning I got when
    the test failed to be disabled because of the above.  I suppose it
    might be useful for some target variants.

            * gcc.target/powerpc/pr104253.c: Add missing dg- before
            require-effective-target.  Prune warning about -mfloat128
            possibly not being fully supported.
    
    (cherry picked from commit ab0f04e4df1b7b312a4c9fa9b4d675778a0bae86)
