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
