I suggest to match library version with sbcl version to avoid nightmare, as
far as I recall upstream doesn't care about ABI stability between releases,
and, for example, .fasl should be recompiled each new release.

Without symlink libsbcl.so -> libsbcl.so.0.0 linking agains that library
will be quite tricky.

Minor remarks:
- minus sign as the first character inside the patch should be ok, but may
  be considered quite suspicious.
- you also need to increase reviosion with that changes.
- I suggest to add diff.noprefix=true to port's git config to avoid prefix

Something like this:
