Do we actually require the soname .so.0, or can we get by with the
more generic version-less .so (and thus continue to work when glibc
bumps to .so.1, provided that bump is backwards compatible for our
usage)?
For Fedora the naked .so file is packaged in glibc-devel. You could
argue that developers are going to need that file in order to build
anything (since it's required to link programs), so I guess it is OK
to remove the ".0".
