external-toolchain: create lib64 symlinks if needed
Create lib64 -> lib and usr/lib64 -> usr/lib symbolic links in the target and staging directories. This is needed for some 64 bits toolchains such as the Crosstool-NG toolchains, for which the path to the dynamic loader and other libraries is /lib64, but the libraries are stored in /lib.
