+Subject: [PATCH] clib: Use build.rs to fix SONAME
+
+Use [`cargo:rustc-cdylib-link-arg`][1] to `build.rs` to fix the SONAME issue
+of cargo.
+
+Removed workarounds in rpm spec and `.cargo/config.toml`.
+
+Changed Makefile to place `-lnmstate` after the source file to fix
+compile issue on ubuntu 20.04 old gcc.
