[v2,0/3] x86: Move CET infrastructure to x86_64

  And removes i686 support now that CET is x86_64 only.   The --enable-cet
now issues an error with i686-linux-gnu.

Adhemerval Zanella (3):
  x86: Move CET infrastructure to x86_64
  i386: Remove CET support
  i386: Fail if configured with --enable-cet
