Can be fixed by the following patch:

	$ diff -u src/corelib/kernel/qcore_unix_p.h_orig src/corelib/kernel/qcore_unix_p.h
--- src/corelib/kernel/qcore_unix_p.h_orig      2018-10-09 19:23:04.124549682 +0200

+Q_CORE_EXPORT int qt_open64(const char *pathname, int flags, mode_t);

Proper buildroot patch will follow (after upstream bug report/change request)...
