How to build a cross_compiler for alpha-ecoff?

[lxf]

Hi,
        I cross-compiled an alpha gcc toolchain.Later ,I found the compiler 
outputs binary in elf64-alpha format.But I want the binary in ecoff format. I 
checked the
cross compiler, it seems it supports alpha-ecoff format too.But,when I try to 
an alpha gcc toolchain for alpha-ecoff,there is some problems.

Below is the files I used to cross-compile the alpha gcc toolchain.
gcc-core-3.1.tar.gz
binutils-2.12.tar.gz
alpha-linux system files

cross-compiling an alpha-elf toolchain:
 % cd $HOME/crossdev/src/binutils-2.12
      % ./configure --prefix=$HOME/crossdev --target=alpha-linux-

% cd $HOME/crossdev/src/gcc-3.1
      % ./configure --prefix=$HOME/crossdev --target=alpha-linux \
                    --with-libs=$HOME/crossdev/src/sysfiles/lib  \
                    --with-headers=$HOME/crossdev/src/sysfiles/include
That's no problem.

cross-compiling an alpha-ecoff toolchain:
 % cd $HOME/crossdev/src/binutils-2.12
     % ./configure --prefix=$HOME/crossdev --target=alpha-linuxecoff
% cd $HOME/crossdev/src/gcc-3.1
      % ./configure --prefix=$HOME/crossdev --target=alpha-linuxecoff
                    --with-libs=$HOME/crossdev/src/sysfiles/lib  \
                    --with-headers=$HOME/crossdev/src/sysfiles/include
          % make
But,then there is a problem that I can't solve. while compiling the file 
libgcc2.c,it reported error.

How can I build an alpha-ecoff cross-compile toolchain?
or How can I get a recompiled alpha-ecoff cross-compile toolchain ?

Thanks!
