I tested linux and found that it failed on a binary with no executable
privileges.  I didn't go to the extra effort of trying to make dependent
.so's nonexecutable.  But, I have confirmed that it is unaffected if a
dependent .so is executable.  So I can't claim that this is completely
a linux compatibility feature.

But, yes, you are correct that I don't think it's worthwhile to rewrite
ldd to deal with this issue.
