+Subject: [PATCH] Change rpath for rustc/rustdoc to rustlib/$TARGET/lib
+
+Rust installs two identical sets of *.so libraries into /usr/lib and
+/usr/lib/rustlib/$TARGET/lib. The former comes with the rustc component,
+/usr/bin/rustc and /usr/bin/rustdoc are linked against them. The latter
+comes with rust-std and are used for binaries dynamically linked against
+Rust libraries (usually compiler plugins, like clippy).
+
+These *.so libraries don't keep stable ABI, so it's better to treat
+them as private. Such libraries should not be exposed at standard paths
+like /usr/lib, but use rpath.
+
+This patch changes rpath for binaries of the rustc component to
+`$ORIGIN/../lib/rustlib/$TARGET/lib`. Duplicate libraries will be still
+installed into /usr/lib, but we can simply remove them when packaging.
