ar: deprecate -T option
Other ar implementations (GNU, LLVM) use -T to mean thin archive rather than use only the first fifteen characters of the archive member name. We support both -T and -f for this, with -f documented as an alias of -T. An exp-run showed that the ports invoking `ar -T` expect thin archives, not truncated names. Switch -f to be the documented flag for this behaviour, and emit a warning when -T is used. The warning will be changed to an error in the future (in main), once ports no longer use -T.
