  Aha.  Looking closely at the error, which takes place while building 
libgcc for the target:

>_eh

  This is the module dealing with exception handling.

  Looking at the sequence of include files here, it's trying to find a
threads package for the target, and choosing a win32 threads package, which
presumably is the nearest thing it knows about.  Look at the gcc configure
command from your script:

>../gcc-${gcc_version}/configure --prefix=$prefix 
>--target=$target --host=$host --build=$build \
>  --with-newlib --enable-languages=$languages \
>  --with-included-gettext --enable-shared --enable-threads

  You may want to change that --enable-threads option, presumably since 
you're compiling for a naked board with no OS you'd want to use 
--disable-threads.  You should probably also replace --enable-shared with
--disable-shared since you probably don't have a dynamic linker on your
target for loading libgcc.a at runtime....
