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. Or I could try to share the 
CXXABI_LDBL_1.3 name although it doesn't correspond to long double in this 
case.

I have no preference, I'll go with whatever people like.
