Title:
  create_elf_tables() doesn't set AT_PLATFORM for 32bit ARM  platforms

Status in QEMU:
  New

Bug description:
  The dynamic linker uses AT_PLATFORM from getauxval to substitute
  $PLATFORM in certain places (man ld.so). It would be nice if it was
  set to 'v6l', 'v7l' and whatever other platforms there are according
  to the chosen CPU or via an environment variable. AT_PLATFORM is not
  guaranteed to be set, so this isn't a major bug, but this is one case
  where it makes things difficult.
