could you try to build the ELF binary without a custom linker script? I
think the built-in one should work too.

could you try to generate the ELF binary like in the existing rule
above? If that works, we could refactor the generic rule to remove the
hard-coded aarch64 flags. If not, move this code and the
"ALL-$(CONFIG_ARCH_BMIPS) += u-boot-bmips.elf" to arch/mips/Makefile
Also don't forget to add new binaries to .gitignore and the Makefile
clean targets.
