[Looks like there are 2 stages involved in that
2mmjnk.txt file that I generated. Before
MACHINE_ARCH is explicitly assigned and after.]

Part of the issue is the ?= use from before the
explicit MACHINE_ARCH assignment blocks any later
?= attempt form changing the result.
I'll note that any of the following executing before the
explicitly MACHINE_ARCH assignment would apparently get
the amd64 value from the /nxb-bin/. . . context, just like
the .if conditional in under investigation:
# grep -r "^\..*MACHINE_ARCH" /usr/src/Makefile* /usr/src/share/mk/ /usr/ports/Mk/ | more

/usr/src/share/mk/bsd.endian.mk:.elif ${MACHINE_ARCH} == "powerpc" || \
/usr/ports/Mk/Uses/gnustep.mk:.if ${MACHINE_ARCH} == "i386"
(I have not tried to figure out which have a chance of
executing before the MACHINE_ARCH explicit assignment.)
