powerpc64le: workaround ieee long double / _Float128 stdc++ bug
-mabi=ieeelongdouble triggers the stdc++ libraries _Float128 support, which then breaks if algorithm is included. For now, explicitly disable _Float128 for such tests. I have opened up GCC BZ 94080 to track this. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
