+Subject: [PATCH] Allow to use -C target-feature=+crt-static on stable rustc
+
+Rust links system libraries statically on musl by default, but we want to
+link dynamically. At the same time we would like to preserve this behaviour
+for consistency with other distros, to not confuse users.
+
+rustc already provides codegen option to change linking, but currently it's
+allowed only for nightly builds. This patch just removes this check and so
+allows to use it even on stable build.
+
+Build dynamically linked binary with rustc or cargo:
+
+    $ rustc -C target-feature=+crt-static hello_world.rs
+    $ RUSTFLAGS="-C target-feature=+crt-static" cargo build
