http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html This is used by disk tools such as disklabel(8) to dynamically decide is the undelyling platform uses a disklabel-in-mbr-partition or not (instead of using a compile-time list of ports). getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the machdep #define LABELUSESMBR. For evbmips, make LABELUSESMBR 1 if the platform uses pmon as bootloader, and 0 (the previous value) otherwise.
