There's no generic ldbl-128 sqrtl implementation in glibc - each ldbl-128 
architecture has its own - meaning the usual approach of #including an 
ldbl-128 implementation with appropriate #defines doesn't apply.  The 
powerpc64le implementation of sqrtf128 is not applicable here because it 
has its own special-case defines to use KFmode instead of TFmode.
