E empty-shared-library-symbols

Although the package does not include any shared libraries, it does have a symbols control file. If you did include a shared library, check that the SONAME of the library is set and that it matches the contents of the symbols file.

SONAMEs are set with something like gcc -Wl,-soname,libfoo.so.0, where 0 is the major version of the library. If your package uses libtool, then libtool invoked with the right options should be doing this.
