  I'm trying to build a 32bit version of GMP in a 32bit system (chroot)
  installed on a x86_64 system. And i'm using 'linux32' to change
  personality, so that programs run on a fake 32bit system.
  
  But when running ./configure in this environment, it found a
  athlon64-unknown-linux-gnu. I have the same result in the 64bit "native"
  environnement:
  
  running config.guess from the x86_64,
  
    $ ./config.guess
    athlon64-unknown-linux-gnu
  
    $ ./configfsf.guess
    x86_64-unknown-linux-gnu
  
  Then adding linux32:
  
    $ linux32 ./config.guess
    athlon64-pc-linux-gnu
  
    $ linux32 ./configfsf.guess
    i686-pc-linux-gnu
  
Please see the text under AMD64 at http://gmplib.org/manual/ABI-and-ISA.html.
