[Buildroot] Error:forced unwind support is required

[Sunil A]

Hi,
   Iam trying to build a cross toolchain for powepc and during the
compliation of glibc-2.3.3,I got stuck with the follwing error:

checking for forced unwind support... no
configure: error: forced unwind support is required

Iam using the follwing :
binutils-2.15
glibc-2.3.3
gcc-3.4.1
glibc-linuxthreads-2.3.3

I have tried googling,but couldn’t get any solution.

Can anybody direct me how to overcome the error??

Thanks
