[Buildroot] [git commit branch/2021.02.x] package/gawk: create awk symlink for host-gawk

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=e16bb3a0da4317814d0926f41b6e5f8b4016f44d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

This is to make sure that host packages that depend on `host-gawk` and that use
`awk` end up using `gawk`, instead of the `awk` symlink installed on the host
system.

On recent Debian-based distributions, `awk` is still symlinked to `mawk` [1].
