The patch "config: verify machine arch flag (b7676fcccab4) " introduces a
verification for specified cpu_instruction_set.
When cpu set to 'auto' as my patch, the below code in config/meson.build
changes it to 'native' and triggers the verification error. However, the
platform couldn't be 'native' or 'generic' for cross build. Changing
cpu_instruction_set from 'auto' to 'native' is unreasonable here. I would like
to send a patch to move the below code to not cross build path.
"if platform == 'native'
if cpu_instruction_set == 'auto'
cpu_instruction_set = 'native'
endif
elif platform == 'generic'
if cpu_instruction_set == 'auto'
cpu_instruction_set = 'generic'
endif
endif"
And I would like to update cpu value in the cross file to aarch64 instead of
auto, to avoid any further possible verification.
