Subject: Re: cxref and __Float128

Looking at https://gcc.gnu.org/onlinedocs/gcc/Floating-Types.html it
seems that there are a few new floating point options.

The patch needs to modify more than one file so I thought it easier to
offer you a patch to test (I don't have glibc 2.26) than to try to
make up a test case myself.
