poky-find-native-sysroot: helper script for locating the native sysroot path 

Various poky scripts make use of binaries from the native sysroot.
This helper script can be used to reduce code duplication, and sets
up some environment variables you can use to identify and obtain
the correct filesystem path to the native sysroot.

It works for both in-tree Poky setups as well as toolchain
installations.

# Find a native sysroot to use - either from an in-tree Poky build or
# from a toolchain installation in /opt/poky. It then sets the variables
# $NATIVE_SYSROOT_DIR to the sysroot's base directory, $PSEUDO to the
# path of the pseudo binary, and $SYSROOT_MODE is set to "in-tree" or
# "toolchain".
#
# This script is intended to be run within other scripts by source'ing
# it, e.g:
#
# SYSROOT_SETUP_SCRIPT=`which poky-find-native-sysroot`
# . $SYSROOT_SETUP_SCRIPT
#
# This script will terminate execution of your calling program unless
# you set a variable $SKIP_STRICT_SYSROOT_CHECK to a non-empty string
# beforehand.
