Description
While working on reproducible builds for openSUSE, I found that
when building the libqt5-qttools package, there were differences between each build.
/usr/lib64/libQt5Designer.so.5.15.1 differs in ELF section .rodata
Results do not differ when using a filesystem with deterministic readdir order.
maybe because
src/corelib/io/qfilesystemiterator_unix.cpp used readdir (2) via QT_READDIR
various Makefiles showed differing ordering of .pri entries
qrc_SmartPhoneWithButtons.cpp has varying order of embedded .png files from rcc.
