Today I reinstalled my Fedora server (Fedora 28 x64), found the
make dependency is missed in current Fedora WireGuard packages resulting in
failing to use Wireguard.

```

```

After I install the make dependency by hand and reinstall WireGuard
packages, anything works fine.
Should the Fedora WireGuard packages add the make dependency? (I have no
experience in maintaining package.)
If no needed, feel free to ignore this email.

Thanks.
