Are folks confusing armv6 vs. armv7? armv6 ports are still built into
packages via qemu.

But official armv7 port builds are done on aarch64 in poudriere(-devel?)
armv7 jails, without use of qemu. The ampere[123] build servers support
aarch32/armv7 native execution and that is put to use in the last year.

https://pkg-status.freebsd.org/?all=1&type=package reports the first ampere
armv7 build as:

default default 130releng-armv7 a51002eeb3d0 32299 29273 294 1791 941 0 stopped:done: Fri, 22 Jul 2022 07:39:45 GMT 66:37:20 ampere3

The first build of armv7 main:

default default main-armv7 p83aeeda2ebb7_s30253da1a 32288 29099  (+27041) 274  (+147) 1948  (+26) 967  (+247) 0 stopped:done: Fri, 29 Jul 2022 21:46:08 GMT 88:40:40 ampere2

The first build of armv7 quarterly:

default quarterly 130releng-armv7 8662e656d870 32236 29152  (+27142) 238  (+140) 1871  (+9) 975  (+237) 0 stopped:done: Fri, 05 Aug 2022 13:04:55 GMT 70:00:06 ampere1

(I've been building armv7 ports that way for longer, but on different
hardware.)
