bootimage.bbclass, zisofs-tools-native: add ability to compress ISO images
The mkzftree is needed to allow ISO images to be compressed with minimal runtime overhead. Below is an example of the savings on a core-image-minimal. Before ls -l: 24117248 core-image-minimal-qemux86-64.iso Using the mkzftree ls -l: 16777216 core-image-minimal-qemux86-64.iso (From OE-Core rev: 808d4371939ec48ed62e0c0b6614b96d61b1f7b8) Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Reviewed-by: Darren Hart <dvhart@linux.intel.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
