  * This is a standalone program that loads and runs the dynamic linker.
  * This program itself must be linked statically.  To keep it small, it's
  * written to avoid all dependencies on libc and standard startup code.
  * Hence, this should be linked using -nostartfiles.  It must be compiled
  * with -fno-stack-protector to ensure the compiler won't emit code that
  * presumes some special setup has been done.
  *
  * On ARM, the compiler will emit calls to some libc functions, so we
  * cannot link with -nostdlib.  The functions it does use (memset and
  * __aeabi_* functions for integer division) are sufficiently small and
  * self-contained in ARM's libc.a that we don't have any problem using
  * the libc definitions though we aren't using the rest of libc or doing
  * any of the setup it might expect.
