Marco, is that the wrong script? That checks for something completely
different:
- It doesn't take into account if the undefined symbol is weak
- It doesn't take into account if the undefined symbol is defined
in a DT_NEEDED library.
The bug reports, on the other hand, were generated using ld.so, which
is more accurate.
