LSB images are not built on the autobuilder. The lsb images folders contain the same image types as the non-lsb ones. ex: http://yocto-ab-master.jf.intel.com/pub/releases/yocto-1.8.rc1/machines/intel-corei7-64-lsb/
This looks like it's been this way for a while. I'll have a fix for it in a bit and will re-roll just the core2 and corei7 lsb builds for the release (as they seem to be the ones without the needed bits).
lsb images are now available and a patch is now in the autobuilder to ensure this doesn't happen again.
LSB images are being build ok now. Setting as verified.
