[PATCH v3] config/arm: correct cpu arch for cross build

[Thomas Monjalon]

20/11/2023 10:24, Joyce Kong:
> The cn10k cross build file sets cpu to 'armv8.6-a' while
> it is armv8.5-a arch.
> Meanwhile, the cpu field in the cross file doesn't take
> effect as config/arm/meson.build controls machine_args
> for march. Then change the 'cpu' value in all arm cross
> files to 'auto'.

What did you change compared to v2?
Please take care of providing a changelog after "---"

I still see the same error on my machine:
config/meson.build:178:8: ERROR: Problem encountered:
Compiler does not support "native" arch flag.
