It depends on how you see it. Users may override many symbols
in the C library as long as they don't use the ones in the C library.
The C library tries very hard to support this. But the 3rd party DSO
may want to use the ones in the C library. My patch tries to address
this. Of course, it doesn't work if there is no symbol versioing or
those symbols are exported somehow.
