Make savedefconfig save to a configured file.
Store BR2_DEFCONFIG in .config, and use it to update the original input defconfig file after updating the configuration. When a config is created by using the BR2_DEFCONFIG=... option, this is saved in the .config file; later runs of savedefconfig will update that same location. It is also possible to configure this place in the interactive configuration. The BR2_DEFCONFIG value itself is not saved into the generated defconfig, since Kconfig considers it at its default. This is intentional, to avoid hard-coding an absolute path in the defconfig. It will anyway be set again when the defconfig is used with the 'make BR2_DEFCONFIG=... defconfig' command. As a side-effect of this change, the *config options have been moved out of the BR2_HAVE_DOT_CONFIG condition. This doesn't make any functional difference, because the .config is still not read for the *config targets. However, the defconfig and savedefconfig targets do need to include .config now, which makes them slightly slower.
