BfinToolChain: compiler error

[Kovács Ferenc <feri1024 at t-email dot hu>]

Hello!

I tried to build the new GCC-4.1.0 for "bfin-elf" but i got an internal compiler error. First i 
built a bfin-toolchain to get the binutils binaries to use when building the new GCC. I 
added this "$BFINTC_BUILD/output/bin" directory to my PATH variable. The GCC config 
options were these: 
--target=bfin-elf --disable-nls --disable-libgcj --disable-multilib --enable-languages=c 
--with-gnu-as --with-gnu-ld --disable-shared --disable-threads --with-newlib
--prefix=$BFINTC_BUILD/output

And the error msg:

Have i missed something important?? 

Thanks for your help.
