We now pass along the toolchain type to all subcommands. This ensures that gdb will load the correct debug information for kernels compiled with Clang, and the following warning won't appear with the GNU toolchain: > WARNING: unknown toolchain 'gdb'. Defaulting to GNU. > Valid values are 'Clang', 'GNU' (default)
