2019.11.3 is EOL, please move to 2022.02.x or 2022.11.x.

With that said, you somehow seem to have changed ARCH to upper case
ARM. Do you have any local modifications?

The host build system type comes from:

package/pkg-autotools.mk:
                --host=$$(GNU_TARGET_NAME) \

Where GNU_TARGET_NAME is defined as:

package/Makefile.in:
# Compute GNU_TARGET_NAME
GNU_TARGET_NAME = $(ARCH)-$(TARGET_VENDOR)-$(TARGET_OS)-$(LIBC)$(ABI)

And where ARCH comes from:

Makefile: ARCH := $(call qstrip,$(BR2_ARCH))

Which for your A9 system gets set in arch/Config.in.arm

config BR2_ARCH
        default "arm"           if BR2_arm
        default "armeb"         if BR2_armeb
        default "aarch64"       if BR2_aarch64
        default "aarch64_be"    if BR2_aarch64_be

So I am not sure how you end up with an upper case 'ARM'?
