When compiling host-jq with gcc 6+, running it gives an immediate segfault.
Reported upstream: https://github.com/stedolan/jq/issues/1598
The issue can be solved by compiling with _GNU_SOURCE as extra preprocessor
define. Once the issue is solved upstream, this change can be reverted.
As the issue will normally be the same for target, apply the same fix there.
