Previously these tools were failing to start with:
xfs_mdrestore: error while loading shared libraries: libxfs.so.0: \
cannot open shared object file: No such file or directory
xfs_quota: error while loading shared libraries: libxcmd.so.0: \
cannot open shared object file: No such file or directory
Extend the 4.2.0-sharedlibs.patch to make those programs work as well.
