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.
