libthread_db is special and should not be stripped. I am not sure if gdb is
able to read the symbols from separate debug file for this shared lib. 
similarily libpthread.so.1 should not be stripped of the symbol table.
I dont know if we strip out symbol tables too if we do then we should spare
these two libraries.
