This is fixed by --default-symver. Not widespread but works as a charm to 
resolve the symbols collision problem.

Of course using hidden visibility for internal symbols is still an important 
thing as it reduces the problem of collisions.
While -Bdirect does not really solve the problem, it might mask it (had xine 
not crashing because of a -Bdirect patched glibc for instance)... when it 
does not mask it the wrong way.
For instance, some parts of X11 relies on symbols' interposing, that is a 
feature more than an error.
