See /usr/local/etc/poudriere.conf:

# By default MAKE_JOBS is disabled to allow only one process per cpu
# Use the following to allow it anyway
# ALLOW_MAKE_JOBS=yes

# List of packages that will always be allowed to use MAKE_JOBS
# regardless of ALLOW_MAKE_JOBS. This is useful for allowing ports
# which holdup the rest of the queue to build more quickly.
#ALLOW_MAKE_JOBS_PACKAGES="pkg ccache py*"

So in your case, adding gcc-12 (or gcc-*) to ALLOW_MAKE_JOBS_PACKAGES might help.
