In previous versions of BSD ar -T was an alias for -f -- use only the
first 15 characters of archive member names. In GNU ar and LLVM ar -T
creates a thin archive.
The -f / old BSD ar -T functionality is not particularly useful, and
ignoring -T still results in a usable and compatible (but not thin)
archive.
An exp-run found a few ports invoking ar -T but they all expect thin
archives. In addition, -T will be used to specify thin archives after
a migration to LLVM-ar.
