It's not correct to do that unconditionally for all the existing 
DEF_GCC_FLOATN_NX_BUILTINS functions.  There should not be a public 
huge_valf128 function any more than a public huge_val function, just 
__builtin_huge_valf128.

Rather, you should add a new DEF_EXT_LIB_FLOATN_NX_BUILTINS.  It should be 
used by the new functions, and by the existing copysign / fabs / nan 
functions.  It should not be used by the existing huge_val / inf / nans 
functions.
