commit 9674bbd0585fc25ccd362f233b83d07ff8f6ff53
Author: Ed Bartosh <ed.bartosh at linux.intel.com>
AuthorDate: Sun Mar 26 20:27:48 2017 +0300

    wic: use wic-tools STAGING_DATADIR as bootimg_dir
    
    If bootloader artifacts are not found in default bootimg_dir
    use wic-tools sysroot for the same purpose. This should
    prevent wic from failing if bootloader artifacts can't be
    found in image native sysroot.
