I have asked the libc-alpha ML about this question,
see reply from Jakub Jelinek ( 
http://sources.redhat.com/ml/libc-alpha/2007-09/msg00073.html)

This should confirm the validity for this check, even if a DSO without 
exported symbols,
sounds pointless to me... but this prevent the linker to "segfault".
