Would simply adding:

else if (TARGET_LONG_DOUBLE_FORMAT != NULL
     && len * TARGET_CHAR_BIT == TARGET_LONG_DOUBLE_FORMAT->totalsize)
   ..

to the end of that if() chain work? (and the other alternatives as well 
of course).

Otherwize, yes, I can't see any other way of handling this problem :-(
