I believe you should match what has been added to strtod_l.c, i.e.:
 {
   return INTERNAL (__STRTOD) (nptr, endptr, 0, loc);
 }
+#if defined _LIBC
+libc_hidden_def (__STRTOLD)
+libc_hidden_ver (__STRTOLD, STRTOLD)
+#endif
 weak_alias (__STRTOLD, STRTOLD)

otherwise calls to strtold_l from within libc.so will go through
PLT.  stdlib/strtold_l.c is only used on
sizeof (double) == sizeof (long double) arches, which I'm afraid
I don't have access to any.
