My guess is that it's because you're using a chroot rather than a jail.
When poudriere creates the jail with 'jail -c' it does not do things
like setup the make.conf or even setup nxb-bin hardlinks.  It only does
this stuff at Jail Startup time (bulk/testport/jail -s).
Checkout jail -s and jail -k rather than using a chroot.

Poudriere sets MACHINE and MACHINE_ARCH in /etc/make.conf.  It seems ok
to me in a Jail.

If I change it to something else it takes the value.

As for chroot it's wrong:

It's not using uname as far as I can tell.  The /etc/make.conf is setup
at Jail Startup time but the jail's /etc/login.conf is setup at 'jail
-c' time currently, which sets UNAME_m and UNAME_p so uname should be
fine anyway:
