Keep in mind that /usr/obj is only used for building the FreeBSD system
itself.

Ports are built in the ports tree. Generally under
/usr/ports/<category>/<portname>/work

You could use unionfs (see mount_unionfs(8)) to overlay a tmpfs over /usr/ports.
I've used unionfs with nullfs to use a single ports tree in multiple jails,
