errors on building the cross-gcc for FRV architecture (frv-elf-gcc)

[Rongkai <zhanrk at 163 dot com>]

hi, everyone:

At recently, i am doing a embedded project based on Fujitsu MB93403 CPU
which has a FRV core. Therefore, i must build a cross gcc compiler. As
we know, RedHat inc is also doing a project to let GNU toolchain, uClibc
and linux support FRV architecture. After they submit their patch,
binutils-2.14, gcc-3.3.x and gdb-6.x have supported frv-elf target. So i
choose the following source packages for building my cross toolchain:

* binutils-2.14.tar.gz
* gcc-core-3.3.3.tar.gz 
* gdb-6.1.tar.gz

When I build and install GNU binutils for frv-elf target, everything is
ok.

However, something is wrong when i build frv-elf-gcc. Here is my
building process details:

/********************************************************************/

And i also try to use gcc-core-3.3.1.tar.gz and gcc-core-3.3.2.tar.gz,
but i get the the same errors as the above. It seems that i need to do
some hack to gcc source codes. Who can help me to correct the error ?

thanks.
