Yep. Can I suggest: -Wl,--as-needed has been added to the default profile's LDFLAGS. This option optimizes the linking process, only linking binaries to libraries that are trully needed. This way, fewer libraries are loaded at runtime and fewer packages need to be rebuilt after library updates. To take advantage of the new default you can either rebuild world now or just allow the system to migrate incrementally as it updates. Please note that setting LDFLAGS="<your flags>" in your make.conf will override the profile defaults. If you want to add additional LDFLAGS it is recommended to use LDFLAGS="${LDFLAGS} <your flags>" instead to avoid this. For more information on --as-needed, read [1].
