  sparc64 work.
  - the syscall wrapper needs to use the "memory"
  clobber specifier to prevent over-optimization.
  - on sparc64, the user address space spans the whole
  64-bit space and therefore the macro
  USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
  overflows to 0
  - stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
  MAX_HEAP_SIZE instead
  - in our situation when kernel and user address spaces
  are separate, the G (global) bit cannot be used
  (there is no point in it anymore)
  - add the DEBUG() macro to stdio.h; DEBUG() uses
  SYS_IO and is a good debugging tool for getting
  early userspace to work
