-Subject: [PATCH] meson: support for custom nm path
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-When cross-compiling target toolchains i.e. binutils are often
-prefixed by its target architecture. This patch gives the user
-to option to specify the nm used during the build process.
