[Buildroot] [PATCH 12/18] checkpackagelib/lib_config.py: CommentsMenusPackagesOrder: check package ordering just before 'if ' statement

[Jerzy Grzegorek]

Because the statement

 if BR2_PACKAGE_..._FOO

(if exist) refers to the foo package, so the line

 source package/foo/Config.in

should go just before that statement.
