Instead of running lsb_release -a, a lsb_release -ir will be run. This will prevent issue with distros that don't have all the needed info in /etc/lsb-release file, in which case lsb_release won't generate an error code. Partial fix for [YOCTO #4071] (From OE-Core rev: 79a2252545ab50c79e00e02c328191c1163f917d) Signed-off-by: Cristian Iorga <cristian.iorga@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
