After a deeper analysis, I came to the conclusion that KDE (kde-frameworks-5-core18:kde-frameworks-5-core18-slot) is the problem here. Qt5 (libQt5Core.so.5) was probably built with getentropy, so it requires Linux 3.17, and EL7 uses Linux 3.10 by default. This is why it doesn't work.
Anyway, rebuilding KDE without getentropy should solve this problem. https://bugs.kde.org/show_bug.cgi?id=417791#c7
