Looks like the FreeBSD naming and the GCC naming are mismatched,
quoting https://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html :
QUOTE
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=, --host=, and --target=.
END QUOTE
If I read that right, mixing the two contexts goes something like:
(Ignoring suffix text and amd64 vs. x86_64 name translations.)
--build=${HOSTARCH}
--host=${ARCH}
--target=${TARGETARCH}
(HOSTARCH vs. --host is a likely source for confusions.)
If right, then the answer to my earlier question would be:
???=HOSTARCH since CONFIGURE_TARGET is used with --build
in some contexts. (As stands HOSTARCH=ARCH 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= ${ARCH:S/amd64/x86_64/}-unknown-${OPSYS:tl}${OSREL}
CONFIGURE_ARGS+= --host=${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="$${_LATE_CONFIGURE_ARGS} --build=${CONFIGURE_TARGET}" ; \
else \
_LATE_CONFIGURE_ARGS="$${_LATE_CONFIGURE_ARGS} ${CONFIGURE_TARGET}" ; \
fi ;
but 2.13 is rather old and the description for the other clause (no --build=) says:
( https://www.gnu.org/software/autoconf/manual/autoconf.html says . . . )
QUOTE
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=alpha-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 ‘build_alias’ is set to that value. Eventually, this historically incorrect behavior will go away.

Messy.
