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

+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.
