        ldbl-128ibm-compat: Introduce ieee128 symbols
    
    IEEE long double versions of strfroml, strtold, and wcstold have been
    prepared, but not exposed (which will only happen when the full support
    for IEEE long double is complete).  This patch adds tests for these
    functions in both IBM and IEEE long double mode.
