[Evidence from inside poudriere bulk -j... -i ports-mgmt/pkg .
Use of native /nxb-bin/. . . leads to MACHINE_ARCH being amd64
instead of armv7 or the like. See later supporting material.]

Those lines come from:

CFLAGS ?=3D -O -pipe
.else
CFLAGS ?=3D -O2 -pipe
.endif
So I used:
# make -dA 2>2mmjnk.txt 1>1mmjnk.txt
and looked for the first -pipe in 2mmjnk.txt. (It is also
the first -O , in this case -O2 .)

It looks like the poudriere builds based on /nxb-bin/. . .
See the amd64 MACHINE_ARCH in the context that shows:
