In trying to make world and kernel on RPI2 at r344613 buildworld ran to
completion, but buildkernel stopped wtih 
--- machdep_boot.o ---
/usr/src/sys/arm/arm/machdep_boot.c:170:34: error: too few arguments to function call, single argument 'cmdline' was not specified
        boothowto |= boot_parse_cmdline();
