dnl ASan assumes no symbols are being interposed, and when that happens,
dnl it's not happy with it. Unconveniently, since Firefox is exporting
dnl libffi symbols and Gtk+3 pulls system libffi via libwayland-client,
dnl system libffi interposes libffi symbols that ASan assumes are in
dnl libxul, so it barfs about buffer overflows.
dnl Using -Wl,-Bsymbolic ensures no exported symbol can be interposed.
