We discussed this on #debian-reproducible today and finally found the reason:
Qt 5.10 started using the getrandom(2) syscall which was introduced in Linux
3.17.

However Debian oldstable (jessie) has 3.16 and it seems some people are still
running this as a host kernel. Mattia (CCed) says he cannot use newer kernels
because of bug #876035.

We can build Qt without the “getentropy” feature and that would lower the
required kernel version to 3.16:
https://code.qt.io/cgit/qt/qtbase.git/tree/src/corelib/global/minimum-linux_p.h#n64

Lisandro, what is your opinion on this?
