Description
When building Qt on Ubuntu 18.04., you'll sometimes find the following line in config.summary:
Compiler: gcc 7.3.0
This is wrong, because the installed gcc version is 7.4.0:
qtrob@rob-desktop:~$ which gcc /usr/bin/gcc qtrob@rob-desktop:~$ ls /usr/bin/gcc* /usr/bin/gcc /usr/bin/gcc-ar /usr/bin/gcc-nm /usr/bin/gcc-ranlib /usr/bin/gcc-7 /usr/bin/gcc-ar-7 /usr/bin/gcc-nm-7 /usr/bin/gcc-ranlib-7 qtrob@rob-desktop:~$ /usr/bin/gcc --version gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0 Copyright (C) 2017 Free Software Foundation, Inc.

It does not seem to happen every time. I just built Qt 5.12.5 and there config.summary is correct. In an older build of Qt 5.12.4, it's wrong again.
