You may well have a suggestion for portmgr_at_FreeBSD.org about combining
materials from independent poudriere bulk runs from separate machines,
but you asked:

Shouldn't packages which are NOARCH be equally available on all 
architectures?

That said nothing about such an idea. I would never have guessed
from your wording what you apparently were actually asking/thinking.
I thought that you thought that armv6 did not try to build NO_ARCH
ports --instead of it being a temporary build problem.

You also asked:

QUOTE
What causes this not to be the case?
END QUOTE

I tried to explain how things actually work currently for the
NOARCH failures, but that was under my misinterpretation if
your intent.

There is no combining of poudriere bulk run results from separate
machines/architectures at this time.  You certainly can ask
portmgr@FreeBSD.org about such ideas.

portmgr might classify it as more-effort/too-complicated-to-manage
than it is worth, expecting that most NOARCH builds work most of
the time on most of the architectures.


But, looking up https://github.com/xtensor-stack/xsimd reports:

QUOTE
The following SIMD instruction set extensions are supported:

Architecture	Instruction set extensions
x86	SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, FMA3+SSE, FMA3+AVX, FMA3+AVX2
x86	AVX512BW, AVX512CD, AVX512DQ, AVX512F (gcc7 and higher)
x86 AMD	FMA4
ARM	NEON, NEON64
END QUOTE

So, for FreeBSD, the following platforms are not supported
from what I can tell:
(from https://www.freebsd.org/platforms/ , other than adding
powerpc64le)

TARGET_ARCH's:

mips, misel
misphf, mipselhf
mipsn32
mips64, misp64el
mips64hf, mips64elhf
powerpc
powerpcspe
powerpc64
powerpc64le
riscv64
riscv64sf
sparc64

[I'm unsure about 32-bit ARMv4/5 "arm" (no v6/v7).]

I'll note that the powerpc*'s are still listed as
Tier 2 for "Projected 14.x" and all the mips*'s
are listed for "13.x". sparc64 is listed only
for 12.x .

That appears to be far from a NO_ARCH context for FreeBSD.
