s390/configs: move CONFIG_DEBUG_INFO_BTF into btf.config addon config
CONFIG_DEBUG_INFO_BTF significantly increases compile time for the kernel. E.g. when changing a single C file compile time for a new bzImage is increased by ~50% if BTF debug info is generated. Therefore remove CONFIG_DEBUG_INFO_BTF from all defconfigs and introduce a btf.config addon config file. Quickly enabling CONFIG_DEBUG_INFO_BTF into the current kernel config can be done by simply invoking make btf.config Reviewed-by: Alexander Gordeev <agordeev@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com> Signed-off-by: Alexander Gordeev <agordeev@linux.ibm.com>
