Bug#991128: libqt5core5a: .pc file missing from installation causing configure scripts to fail

[nbi <nbi.vegas@gmail.com>]

Package: libqt5core5a
Version: 5.15.2+dfsg-9
Severity: serious
Tags: a11y ftbfs
Justification: 7

The package installs correctly as per dpkg, but the corresponding .pc file is missing. This is serious because
many packages require a configure script to be run which checks for the presence of Qt5 components by invoking
pkg-config. This check will fail even though the Qt5 is installed. This is true for all *Qt5* libraries in Bullseye.
