I haven't built the embedded version of CLFS. I saw a lot of work done to it about a year ago so hopefully it is in good shape. I did build the 'regular CLFS' for ARM. I got it to work but it takes a very long time to build: http://lists.cross-lfs.org/pipermail/clfs-support-cross-lfs.org/2011-August/001246.html Good luck.
