qt5-widgets fails to build

[Chris Nicol]

Dear "kde"

I am tring to build //usr/ports/graphics/xpdf, a simple programme, 
apparently, which calls for the build of x11-toolkits/qt5-widgets, for 
which you are maintainer according to the Makefile:

# $FreeBSD: head/x11-toolkits/qt5-widgets/Makefile 531601 2020-04-13 
12:35:58Z tcberner $

This build is on a SunBlade 100 running FreeBSD 12.1. This is an old 
machine, so the build goes on for some time, but results in a failure at 
the linker stage - "undefined reference to QAbstractSlider", with the 
following crash dump file:
