I can reproduce problem using:

BR2_powerpc=y
BR2_powerpc_440=y
BR2_TOOLCHAIN_BUILDROOT_LARGEFILE=y
BR2_TOOLCHAIN_BUILDROOT_INET_IPV6=y
BR2_TOOLCHAIN_BUILDROOT_INET_RPC=y
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y
BR2_PTHREADS_NONE=y
BR2_BINUTILS_VERSION_2_24=y
BR2_GCC_VERSION_4_9_X=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_LIBFFI=y

In add, I found this patch :
  http://lists.busybox.net/pipermail/buildroot/2012-November/061976.html

It is seems is had never been applied and it should solve this issue.
