commit: https://git.buildroot.net/buildroot/commit/?id=b28d77789a4ba327532674efd6250b8634a99feb
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The nc -> netcat symlink is not created if nc exists already, e.g.
from busybox.

For netcat itself this is not needed, it is always installed.
