You do not need even a jail for this. Base cc -m32 works on amd64 for
long time, and 32bit binaries can be executed from host environment,
assuming all third-party libs are provided somewhere in the 32bit

The environment with regard to the hardware configuration should be
identical to modern i386-arch machine with SSE2.  Incompatibilities are
considered as bugs and are usually fixed fast when reported.
