[PATCH] scripts: kconfig: merge_config.sh: fix unexpected operator warning

[Weizhao Ouyang]

Fix a warning for:

$ ./scripts/kconfig/merge_config.sh .config extra.config
Using .config as base
Merging extra.config
./scripts/kconfig/merge_config.sh: 384: [: false: unexpected operator

The shellcheck report is also attached:

if [ "$STRICT" == "true" ] && [ "$STRICT_MODE_VIOLATED" == "true" ]; then
               ^-- SC3014 (warning): In POSIX sh, == in place of = is undefined.
                                                        ^-- SC3014 (warning): In POSIX sh, == in place of = is undefined.

Fixes: dfc97e1c5da5 ("scripts: kconfig: merge_config.sh: use awk in checks too")

Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped or
reverted. Patches applied to an "unstable" branch are accepted pending
wider testing in -next and any post-commit review; they will generally
be moved to the main branch in a week if no issues are found.

Best regards,
