Not yet, will do after Easter.

Similarly to ldbl-128 and ldbl-64-128.  The former is a directory with
support for IEEE quad long double (ldbl-128ibm would be for IBM 2xdouble
long double format), the latter contains wrappers around dbl-64 and
ldbl-128* functions so that both sizeof (double) == sizeof (long double)
and sizeof (double) < sizeof (long double) is supported.

That should be dbl-64/wordsize-64 subdir instead IMHO.
