gcc-plugins: remove support for GCC 4.9 and older
The minimum GCC version has been bumped to 5.1, so we can get rid of all the compatibility code for anything older than that. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Kees Cook <keescook@chromium.org> Link: https://lore.kernel.org/r/20210922182632.633394-1-ardb@kernel.org
