Subject: kconfig: error out if recursive dependencies are found
X-Git-Tag: v2.6.22-rc1~1007^2~2

kconfig: error out if recursive dependencies are found

Sample:
config FOO
	bool "This is foo"
	depends on BAR

config BAR
	bool "This is bar"
	depends on FOO

This will result in following error message:
error: found recursive dependency: FOO -> BAR -> FOO

And will then exit with exit code equal 1 so make will stop.
