    Description

      Building on Linux with address sanitizer turned on like this:

      configure -opensource -confirm-license -developer-build -nomake tests -nomake examples -debug -qtnamespace QtNS -sanitize address
make -j8 module-qtbase

      results in:

      /home/erik/dev/qt5.9/qtbase/src/corelib/plugin/qlibrary_unix.cpp:279: error: undefined reference to 'dlsym'
/home/erik/dev/qt5.9/qtbase/src/corelib/plugin/qlibrary_unix.cpp:62: error: undefined reference to 'dlerror'
/home/erik/dev/qt5.9/qtbase/src/corelib/plugin/qlibrary_unix.cpp:297: error: undefined reference to 'dlsym'
collect2: error: ld returned 1 exit status
Makefile:1128: recipe for target '../../lib/libQt5Core.so.5.9.1' failed

      adding -ldl fixes it.
