i386 jail on amd64

Tracing the processes with ktrace -d shows this happening inside
csup:

 63259 csup     NAMI  "/usr/local/tinderbox/jails/6.4-RELEASE-i386/src/bin/kill/Makefile"
 63259 csup     RET   _umtx_op 0
 63259 csup     RET   _umtx_op 0
 63259 csup     RET   access -1 errno 2 No such file or directory
 63259 csup     CALL  _umtx_op(0x800e19280,0x11,0,0,0)
 63259 csup     CALL  lstat(0x800f12040,0x7fffff3fae00)
 63259 csup     RET   _umtx_op 0
 63259 csup     NAMI  "/usr/local/tinderbox/jails/6.4-RELEASE-i386/src/cddl/contrib/opensolaris/cmd/dtrace/test/tst/common/clauses/err.D_IDENT_UNDEF.arrtup.d"
 63259 csup     CALL  access(0x800f02080,F_OK)
 63259 csup     CALL  _umtx_op(0x800e192a0,0x8,0x1,0x800e19280,0)
 63259 csup     NAMI  "/usr/local/tinderbox/jails/6.4-RELEASE-i386/src/bin/kill/kill.1"
 63259 csup     RET   lstat -1 errno 2 No such file or directory
 63259 csup     RET   access -1 errno 2 No such file or directory
 63259 csup     CALL  _umtx_op(0x800e192a0,0x9,0,0,0)

Is tinderbox meant to create /usr/local/tinderbox/jails/6.4-RELEASE-i386/src
before calling csup? It never does. Additionally, csup never actually logs
any "could not create file" errors.

Something seems to be pretty fundamentally wrong here. I've tried creating
src by hand but this is removed when running ./tc createJail again.
