[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 ?=3D use from before the
explicit MACHINE_ARCH assignment blocks any later
?=3D 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:
