powerpc64le: add -mno-gnu-attribute to *f128 objects and difftime
In practice, this flag should be applied globally, but it makes a good sanity check to ensure ibm128 and ieee128 long double files are not getting mismatched. _Float128 files use no long double, thus are always safe to use this option. Similarly, when investigating the linker complaints, difftime makes trivial, self contained, usage of long double, so thus it is also explicitly marked as such.
