Hi List , Thanx for such a quick reply !
I have already the native gcc(2.95.3) built compiler . I am trying 
to build the Cross Compiler for arm .The compiler just builds 
smooth for Little endian (thats the default build IIRC)
We are able to build the kernel in little endian format . Now i 
need to build the kernel in in big -endian format 'cause my board 
understands only big-endian.
So i tried adding the -mbig-endian option to compiler and also -EB 
to the GAS . But it fails to build a big endian format .
It gives the error as follows

What cud be the problem ?? And can u please suggest the method to 
make the compiler in the big-endian format ??

Thanx in advance
