kconfig: allow overriding symbols
Allow config variables in .config to override earlier ones in the same file. In other words, # CONFIG_SECURITY is not defined CONFIG_SECURITY=y will activate it. This makes it a bit easier to do cat original-config myconfig myconfig2 ... >.config; and run *config as expected.
