+Subject: [PATCH] Add need_rpath target option to force RPATH generation
+
+This adds a `need_rpath` option to the target options in order to implicitly
+have the equivalent of `-C rpath` specified by default for final products
+(executables and dynamic libraries), so that RPATHs are always added.
+
+We have to skip this step in the bootstrap phase as it does its own manual
+RPATH additions, but unfortunately there's no clean way to detect this.
+As such, we have to resort to checking the `RUSTC_BOOTSTRAP` variable.
+Hacky hacky!
