subversion checks whether build with boost during do_configure. If boost
exists on build machine, it causes configure-unsafe QA issue:
| ERROR: subversion-1.12.0-r0 do_configure: QA Issue: This autoconf log
| indicates errors, it looked at host include and/or library paths
| while determining system capabilities.
| Rerun configure task after fixing this. [configure-unsafe]
Add a PACKAGECONFIG 'boost' to fix the issue.
