You should specify all three here.  Sorry if I wasn't clear about that
before.  --build=i686-pc-cygwin --host=i686-pc-mingw32
--target=i686-pc-mingw32.  Without --host it assumes that host=build,
and tries to make a Cygwin binary, which fails since you're using mingw
gcc.  This is only necessary for toolchains, for regular libraries (e.g.
gmp and libiconv) you should only need --host and --build when
cross-compiling.

I didn't mean to discourage you from cross compiling binutils the way
you currently are, only to point out that doing "configure
i686-pc-mingw32" is discouraged by autoconf people and that the
preferred way is to spell out host, target, build explicitly.
