reduced testcase is: 
 
/usr/bin/ld --eh-frame-hdr -m elf_i386 -shared -o wmfthumbnail.so \ 
--no-undefined --allow-shlib-undefined --as-needed \ 
./wmfthumbnail_la.all_cpp.o \ 
/usr/lib/libqt-mt.so /lib/libpthread.so.0 /usr/X11R6/lib/libX11.so \ 
-soname wmfthumbnail.so 
 
without --as-needed option it reports only valid undefined references.
