compatibility is still broken as we add new symbols to libc. Those
symboles are __sbmaskrune, __sbistype, __sbtoupper and __sbtolower.
The latter three are directly referred by binaries use ctype(3) family
functions (see include/ctype.h for details). This means if a binary
built on 6.3, it uses these symbols that are not available on older
system.
- As this has been in 6 for a month, I intentionally leave these symbols
in libc but map them to original version. So binary built after 602113
will not be broken after this commit.
- Bump __FreeBSD_version for this back-out
