[Added: The original cross-build via poudriere-devel and qemu-user-static
did not get this problem. I give details later. Sumamry: Looks like -O2
was used for the cross build and -O was used for armv7 native. The
difference is likely(?) from my materials but not supporting both ways of
building is likely a problem with the port(?).]

I went back and looked at the amd64 -> armv7 cross-build
( that used teh poudriere-built /nxb-bin/usr/bin/ ) and it
did not complain:

. . .
So I diff'd the logs and found the following (selective extraction):
(- for amd64 -> armv7; + for armv7)
-Poudriere version: 3.2.99.20180601
+Poudriere version: 3.2.99.20181024
This is was expected but may mean that I need to wait
until the armv7 has 3.2.99.20181024 and I try via
it.
-SHELL=/bin/csh
-UNAME_p=armv7
-UNAME_m=arm
-ABI_FILE=/usr/lib/crt1.o
+SHELL=/bin/sh
The SHELL's I expected but the other 3 lines I did not.
But the 3 lines may only occur under qemu-user-static
style use.
-QEMU_EMULATING=1
Expected.
In CONFIGURE_ENV:
amd64 -> armv7: CCASFLAGS having -O2
armv7: CCASFLAGS having -O
In MAKE_ENV:
amd64 -> armv7: CFLAGS having -O2
armv7: CFLAGS having -O
(The -O2 vs. -O context differences may well be important
to the behavior.)
(I'll not list /nxb-bin/. . . path use vs. not.)
Later:
-MACHINE=arm
-MACHINE_ARCH=armv7
-ARCH=${MACHINE_ARCH}
-.if ${LDFLAGS:M-fuse-ld=*lld*} || ${/usr/bin/ld:L:tA} == /usr/bin/ld.lld
-LDFLAGS+= -Wl,--no-threads
-.endif
(That last was part of an experiment with avoiding a
user-arm-static hangup.)
-_SMP_CPUS=28
+_SMP_CPUS=4
I'll stop with that. It looks to me like -O2 vs. -O
would be the likely distinction. While my materials
probably caused that difference(?), the port likely
should support both ways of building(?).
