Here's the reason why:

As you can see, using a LD_PRELOAD trick makes the library appear in the
libraries list. Since fakeroot uses such a trick, this causes an error
message in dpkg-shlibdeps, but since there is no .shlibs file for the
library, nothing is added to ${shlibs:Depends} and since it is a LD_PRELOAD
trick, there is no real library dependency on that file.
Thanks,
Timshel
