Not all toolchains rely on autoconf to get that information.

BTW, I'm not opposed to adding stuff to configure.in if it helps
with the cross-compilation, but I'm cautious about replacing stuff
with other stuff if the impact on other platforms is unclear.

Adding AC_CANONICAL_SYSTEM doesn't seem risky to me,
but using it as replacement for AC_CANONICAL_HOST
seemed strange as they aren't equivalent.
