bug#72967: PHP not building

[Andreas Enge]

Hello,

after the core-updates merge, I noticed that php does not build any more.
I thought that maybe commit adfb0be57fd036dded0225a3ff1eb13f6646ee00, which
had updated the version from 8.3.9 to 8.3.10, was to be blamed; has his
gone through QA?

In any case, reverting the commit does not help. So maybe it is a problem
between the former core-updates and master.

The first problem is that gd requires to add fontconfig, freetype and
libjpeg through the Requires.private field of its pkg-config file.

After doing this, one of the tests fails:
