ia64-elf and i386-elf fail to build

[Nick Clifton]

Hi Guys,

  The ia64-elf and i386-elf targets currently fail to build for me using
  the mainline sources.  The symptom is a seg-fault when running the
  self tests:

    ./xgcc <...> -xc -S -c /dev/null -fself-test
    <built-in>: internal compiler error: Segmentation fault

  The cause appears to be an attempt to register a builtin type using
  the float128_type_node, which is NULL for these particular targets:

    gcc/config/ia64/ia64.c:10373
    gcc/config/i386/i386.c:33347

  Presumably float128_type_node should not be NULL, but I am not sure
  how to fix this.  Any suggestions ?

Cheers
  Nick
