I would rather we limit the scope to libacpi.
How do you cross-compile tools?
If CONFIG_ARM_64 is usable within Makefile, we can do something like:
MKDSDT_CFLAGS-$(CONFIG_ARM_64) = -DCONFIG_ARM_64
MKDSDT_CFLAGS-$(CONFIG_X86) = -DCONFIG_X86
Then add MKDIST_CFLAGS-y to mkdsdt's build rune.
Change mkdsdt.c source code accordingly.
