As it's stated here [1]

*Caution:* Reading the documentation, you may be tempted to try the  
--no-as-needed option as a "quick fix" workaround, but it's generally  
the not the right fix. If you aren't able to get a package working  
with the --as-needed and --no-copy-dt-needed-entries options enabled,  
it's best to submit a bug report and get expert attention. (It may be  
a sign of deeper flaws in the code or linking strategy of the package.)
