The related strncpy() for custom_builtin_name[*] may set 5 none-zero characters, which cause custom_builtin_name[*] none-zero terminated. But error() assumes custom_builtin_name[*] is always zero terminated. So add additional '\0' byte for custom_builtin_name[*]. ChangeLog: * config/nios2/nios2.c (custom_builtin_name): Let it always be zero terminated string.
