[Buildroot] Problem with buildroot and external toolchain

Here is what I have for an external glibc-based toolchain:

BR2_TOOLCHAIN_EXTERNAL_LIB_C="libc.so.6"
BR2_TOOLCHAIN_EXTERNAL_LIBS="ld.so.1 libcrypt.so libdl.so libgcc_s.so libm.so libnsl.so libnss_dns.so libnss_files.so libpthread.so libresolv.so librt.so libstdc++.so libutil.so"

BR2_TOOLCHAIN_EXTERNAL_PATH="/opt/toolchains/gcc-3.4.5-glibc-2.3.6/powerpc-7450-linux-gnu"
BR2_TOOLCHAIN_EXTERNAL_PREFIX="powerpc-7450-linux-gnu"

The libraries will be copied from:

  $(BR2_TOOLCHAIN_EXTERNAL_PATH)/$(BR2_TOOLCHAIN_EXTERNAL_PREFIX)/lib

Hope that helps.
