From: Mark Hatle <mark.ha...@windriver.com>

When displaying the buildcfg for the end user, add in processing
of the multilib variants.  Only the items that are not the same as
the DEFAULTTUNE are displayed.

I.e.:
Build Configuration:
BB_VERSION        = "1.19.0"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "CentOS-6.4"
DISTRO_VERSION    = "oe-core.0"
MACHINE           = "qemux86-64"
DEFAULTTUNE       = "x86-64"
TARGET_SYS        = "x86_64-oe-linux"
TUNE_FEATURES     = "m64"
TARGET_FPU        = ""
lib32:  DEFAULTTUNE       = "x86"
lib32:  TARGET_SYS        = "i586-oe-linux"
lib32:  TUNE_FEATURES     = "m32"
meta              = "master:1975f3d7bbeb184489a5d0a2e0de231f317d3e1b"

The order of the displayed elements was changed slightly to group the
host information together, as well as group the target information
together.
