[PATCH 0/4] Commits enabling x32 infrastructure in the master branch

[nitin.a.kamble]

From: Nitin A Kamble <nitin.a.kamble@intel.com>

These commits add infrastructure to the oe-core/yocto to add the meta-x32 layer to build x32 images. core-image-minimal has been tested to work with this commits

=== How to build an image with x32 binaries

Add this layer on top of yocto/oe-core
  http://git.pokylinux.org/cgit/cgit.cgi/experimental/meta-x32/
Add these lines in your conf/local.conf
  MACHINE = "qemux86-64"
  DEFAULTTUNE = "x86-64-x32"
  TUNE_PKGARCH = "x86-64-x32"

And build the minimal image with command:
  bitbake core-image-minimal 

And then run it with qemu with this command:
  runqemu qemux86-64 core-image-minimal


=== How to know if your binaries/libraries are x32:
  Run the file command to know what type of elf binary is it. It should 
  be 32bit x86-64 elf binary as seen here:
  $ file bin/busybox 
bin/busybox: setuid ELF 32-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.35, not stripped

  $file usr/lib/libz.so.1.2.5 
usr/lib/libz.so.1.2.5: ELF 32-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped

The following changes since commit f94b781695cd8fa387daff16ecbf3987a0883018:

  poky.conf: explicitly referenced preferred linux-yocto version (2011-07-27 09:56:56 -0700)

[PATCH 1/4] toolchain-scripts & other classes: add TARGET_LD_ARCH & TARGET_AS_ARCH vars

[nitin.a.kamble]

From: Nitin A Kamble <nitin.a.kamble@intel.com>

This is comming from x32 need to pass special parameters to ld & as.
