And that would involve new syntax in glibc Versions files, as discussed in 
<https://gcc.gnu.org/pipermail/gcc/2021-October/237510.html>, to give the 
binary128 versions of certain functions (functions added after the initial 
_Float128 support was added to glibc but before it gets added for these 
other ABIs) the right symbol version.
