Can you try this patch? RANLIB_FOR_BUILD was defined nowhere, hence it 
was passed as empty to configure and detected (incorrectly) to be 
"ranlib" instead of "owranlib".

This dates back more or less to the dawn of time^Whaving a separate 
directory for build-side libraries 
(http://gcc.gnu.org/ml/gcc-patches/2001-11/msg01576.html).  This evolved 
into more complete support over time (including e.g. building 
flex/bison/texinfo that can be used when building other tools, which in 
turn evolved into toplevel fixincludes), but this bit was always missing.

(It might even be that it worked with Cygnus configure, and stopped 
working after autoconfiscation).

If it works, feel free to apply it.
