           Summary: [PowerPC] Buildroot uses wrong external toolchain
                    libraries for non-generic architecture variants
           Product: buildroot
           Version: 2013.08
          Platform: PC
        OS/Version: All

Using Codesoucery external toolchain, and architecture variant 8548 / e500v2,
toolchain libraries are copied from powerpc-linux-gnu/libc/nof but should be
copied from powerpc-linux-gnu/libc/te500v2. 

Library powerpc-linux-gnu/libc/nof/usr/lib/libstdc++.so contains 'lwsync'
instruction which is invalid on e500v2 and causes Invalid Instruction fault for
every c++ based application.

I tested the temporaty workaround (copying te500v2 dir to nof dir) and it
solved the bug.

I suppose that this bug might involve all PowerPC architecture variants.
