I should also mention that arm-trusted-firmware and u-boot packages have
support for cross-building when not using --target=ARCH. e.g. Building
these packages on x86_64 builds working binaries for the aarch64 boot
firmware.

Maybe somehow the internal cross-building support is interfering with
how the --target=ARCH style cross-building works?
