Only some internal bootstrap utilities for sh are built because sh
is a build-tool. It is these utility that need to be portable and
not use new features like %t.
$ grep %t /usr/src/bin/sh/*
/usr/src/bin/sh/arith.y:%token ARITH_NUM ARITH_LPAREN ARITH_RPAREN
/usr/src/bin/sh/jobs.c: fmtstr(s, 64, "[%td] ", jp - jobtab + 1);
/usr/src/bin/sh/mksyntax.c: fprintf(cfile, " %td,\n", p - digit);
^^^^^^^^^^ bootstrap utility ^^ unportable
