What's your rationale for keeping this in a separate version block

Powerpc already has those symbols in CXXABI_LDBL_1.3 (for a type that
isn't __float128 but (de)mangles that way). That doesn't prevent from
using CXXABI_1.3.9 in the x86/ia64-specific file though, so I can do
that if you prefer. If a new target implements __float128 in 4.11 or
4.12, they will have to refine the configure test and provide a
different .ver file to avoid adding symbols to an old version.
Fair enough. Let's stick with your approach then, but drop the 1.3.9
from the name.
Why is __float128 handled as a target type, anyway? I'd think it ought
to be a standard type that just isn't supported on all targets, like
__int128.
