See UPDATING about upgrading clang for dynamic linking. . allow executables on ramdisk to be dynamically linked; this means putting a few required shared libraries and ld.elf_so on the ramdisk. . this makes the ramdisk (usage) smaller when they are dynamic, but bigger when they're not. . also we can safely ditch newroot and call mount directly as that is all newroot does. . create proto.common to share a bunch of entries between small/nonsmall cases
