Looks like the FreeBSD naming and the GCC naming are mismatched,
quoting https://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html :

There are three system names that the build knows about: the machine you =
are building on (build), the machine that you are building for (host), =
and the machine that GCC will produce code for (target). When you =
configure GCC, you specify these with --build=3D, --host=3D, and =
--target=3D.

If I read that right, mixing the two contexts goes something like:
(Ignoring suffix text and amd64 vs. x86_64 name translations.)
--build=3D${HOSTARCH}
--host=3D${ARCH}
--target=3D${TARGETARCH}
(HOSTARCH vs. --host is a likely source for confusions.)
If right, then the answer to my earlier question would be:
???=3DHOSTARCH since CONFIGURE_TARGET is used with --build
in some contexts. (As stands HOSTARCH=3DARCH seems to be
required but I was after the more conceptual classification.)
Earlier I probably should have shown the code:
.if defined(CROSS_TOOLCHAIN)
CROSS_HOST=3D =
${ARCH:S/amd64/x86_64/}-unknown-${OPSYS:tl}${OSREL}
CONFIGURE_ARGS+=3D --host=3D${CROSS_HOST}
.endif
as well.
Hmm. Looking I see:
if [ -z "`${CONFIGURE_CMD} --version 2>&1 | ${EGREP} -i =
'(autoconf.*2\.13|Unrecognized option)'`" ]; then \
_LATE_CONFIGURE_ARGS=3D"$${_LATE_CONFIGURE_ARGS} =
--build=3D${CONFIGURE_TARGET}" ; \
else \
_LATE_CONFIGURE_ARGS=3D"$${_LATE_CONFIGURE_ARGS} =
${CONFIGURE_TARGET}" ; \
fi ;
but 2.13 is rather old and the description for the other clause (no =
--build=3D) says:
( https://www.gnu.org/software/autoconf/manual/autoconf.html says . . . =
)

For backward compatibility, configure accepts a system type as an option =
by itself. Such an option overrides the defaults for build, host, and =
target system types. The following configure statement configures a =
cross toolchain that runs on NetBSD/alpha but generates code for GNU =
Hurd/sparc, which is also the build platform.
./configure --host=3Dalpha-netbsd sparc-gnu
In Autoconf 2.13 and before, the variables build, host, and target had a =
different semantics before and after the invocation of =
AC_CANONICAL_BUILD etc. Now, the argument of --build is strictly copied =
into build_alias, and is left empty otherwise. After the =
AC_CANONICAL_BUILD, build is set to the canonicalized build type. To =
ease the transition, before, its contents is the same as that of =
build_alias. Do not rely on this broken feature.
For consistency with the backward compatibility scheme exposed above, =
when --host is specified but --build isn't, the build system is assumed =
to be the same as --host, and =E2=80=98build_alias=E2=80=99 is set to =
that value. Eventually, this historically incorrect behavior will go =
away.
