<br>
The problem was that we were setting IsUsedInRegularObj based on<br>
symbols but IsUsed based on relocations. I fixed that by setting<br>
IsUsed based on symbols. That matches what bfd and gold do and is<br>
simpler. IsUsed now just means that one of the symbol in that .so<br>
IsUsedInRegularObj.<br>
<br>
With that, the attached patch should fix the problem that is blocking<br>
adding version info, no?<br>
