actually this was the procedure i always used for cross-compilation.
Now i know it is wrong, But for gcc3.4 and glibc 2.3.4 , it used to
work very well. I used to build the entire toolchain in this manner
and the executables worked fine .Anyways i have built the new
powerpc-deb-linux-gcc and it supports the -mlong-double-128 options .
thanks for the help Daniel and Lior.
But now a new problem has cropped up namely forced unwind . On few of
the threads i see that it is binutils bug, but i am not sure in this
case.Can you help me in this regard.
