+Subject: [PATCH] Add RUST_TARGET variable
+
+Add RUST_TARGET environment variable through AC_ARG_VAR to allow the
+user to override the rust target name. Indeed, using $host when
+cross-compiling is not always the good option especially when vendor
+part of target is not set to unknown but to another value such as
+buildroot.
+Indeed, in this case aarch64-buildroot-linux-gnu won't be recognised as
+a valid target by rust/cargo.
