Subject: [PATCH 6/7] gnu: qt@4: Update build config.

From: Efraim Flashner <[email-masked]>
Date: Wed, 24 Oct 2018 14:41:33 +0300

* gnu/packages/qt.scm (qt@4)[arguments]: Substitute hardcoded '/bin/ls'
invocation. Add configure-flags to not build the examples or demos.
Don't use the precompiled headers.
