Subject: [PATCH] depends: Avoid `warning: "_FORTIFY_SOURCE" redefined` for
 `libevent`

On Alpine Linux 3.12.3, compiling the `libevent` package produces
multiple warnings:
```
$ gmake -C depends -j $(nproc) libevent
<snip>
<command-line>: warning: "_FORTIFY_SOURCE" redefined
<built-in>: note: this is the location of the previous definition
<snip>
```
