From: "Gabriel F. T. Gomes" <gabriel@inconstante.eti.br> Ensure the correct ldouble abi flags are applied to ibm128 files and nldbl files. Remove the IEEE options if used, and apply the flags used to build ldouble files which are ibm128 abi. nldbl tests are a little tricky. To use the support, we must remove all ldouble abi flags, and ensure -mlong-double-64 is used.
