[OE-core] [PATCH 4/4] scripts/postinst-intercepts: create separete hooks for multilib

[Laurentiu Palcu]

When using multilib, the hooks for lib32/lib64 must be different because
the libdir/base_libdir point to different locations. Nothing has to be
done in the postinstalls for this. When a hook is installed, it will be
detected automatically if this is a ML package (from the libXX- package
prefix) and a separate hook will be created.
