    rs6000/test: Fix empty TU in some cases of effective targets [PR106345]

    As the failure of test case gcc.target/powerpc/pr92398.p9-.c in
    PR106345 shows, some test sources for some powerpc effective
    targets use empty translation unit wrongly.  The test sources
    could go with options like "-ansi -pedantic-errors", then those
    effective target checkings will fail unexpectedly with the
    error messages like:

      error: ISO C forbids an empty translation unit [-Wpedantic]

    This patch is to fix empty TUs with one dummy function definition
    accordingly.

            PR testsuite/106345

    gcc/testsuite/ChangeLog:

            * lib/target-supports.exp (check_effective_target_powerpc_sqrt):
Add
            a function definition to avoid pedwarn about empty translation
unit.
