This commit backports an upstream commit to fix the build of pulseview with recent Qt versions. Note that pulseview has a 0.4.2 version (newer than our 0.4.1) but it doesn't have the fix we need. And 0.4.2 now requires additional Qt translation tools, so the update to 0.4.2 is anyway not straightforward. Fixes: http://autobuild.buildroot.net/results/c9e27a91905dfda0ba1ddb12c7910316d3ee82ef/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
