Per discussion with Adam, don't make this an LB_ variable since it's not actually part of live-build; instead we will look to pass it into the environment through launchpad-buildd 8 years ago			`case $IMAGE_TARGETS in`
Support passing IMAGE_FLAVORS in the environment, to limit which images are output as part of a build; particularly useful for ubuntu-cpc builds which output multiple image types. 8 years ago			`""\|qcow2)`

Use xz -T4 -0 instead of pxz Test showed very little difference in file-size between -0 and -9 while both compression and decompression need much less memory and compression needs less CPU time for -0. Supported xz versions before 5.2 also accept the -T4 option but ignore it. Also depend on xz-utils instead of on pxz.
