I did not ask for the patch, but it matches some typical situations I
experience at work. Building kernels out-of-source w/ 'O=' but modifying
.config with the '--file' option does not feel "natural". And 'O=' in
scripts/config allows reusing make arguments (readline/bash's ESC-n ESC-.).
Having the 'O=' argument, it might allow fixing the '--refresh' option to
support out-of-source builds.
Thus, no really great points from me.
Kind regards,
Nicolas
