 It should then be called <arch-tuple>-ldd, like the crosstool-ng one, right?

 It's useful in the same way that cross-gdb is useful.

 However, there sure is something broken about it: it should use the staging 
directory as sysroot, not /.  This would also fix the ncurses case.  
(Actually, also the cross-gdb could benefit from this; now you always have to 
do a 'set solib-absolute-prefix ...' for remote debugging.)
