gnunet build fails (Slackware)

[Slack Coder]

Hi,

Gnunet is failing to build for me on the latest master version 
(b1bd228cfc7847d06ca35cbec5ec48c3942fea41).

The build is on Slackware64-15.0 with meson upgraded (1.3.0) from 
Slackware64-current.  I also get an error about a missing reference to 
pthread when postgresql is not included as a dependency.

You may find a Dockerfile to reproduce the bug and its build output 
attached.

```
