kbuild: adding symbols in Kconfig and defconfig to TAGS
I'm using TAGS generated from "make TAGS" to read the kernel source code. When I met a ifdef block #ifdef CONFIG_FOO ... #endif in the soruce code I would like to know the meaning CONFIG_FOO to decide whether I should read inside the ifdef block or not. meaning CONFIG_FOO is well documented in Kconfig. So it is nice if I can jump to CONFIG_FOO entry in Kconfig from "#ifdef CONFIG_FOO" with the tag jump. Here is the patch to add symbols in Kconfig and defconfig to TAGS in "make TAGS" operation.
