Just think for a moment how exactly will your shared library depend
on a specific symbol version in C or thread libraries if no
dependencies on libc.so.6 and libpthread.so.2 were recorded in the
first place? When no -lc or -lpthreed were seen by ld at all?
The symbol is defined by a name, version and library's SONAME.
