Linux repo has under `tools/include/nolibc` very simple include files that we can use to generate very small binaries that don't depend on libc. To make things even better, since Linux 6.6 it supports all the architectures we support in runc, which is just beautiful. The runc-dmz binary on x86_64 before this patch (on my debian host) was taking 636K, with this patch it takes only 8K. Signed-off-by: Rodrigo Campos <rodrigoca@microsoft.com>
