/bin/sh: lz4c: command not found
Also, several of the blackfin builds started failing due to a
issue, e.g. http://kisskb.ellerman.id.au/kisskb/buildresult/9101322/:
Invalid Compression Type - valid names are: none, bzip2, gzip
Usage: /usr/local/bin/mkimage -l image
-l ==> list image header information
/usr/local/bin/mkimage [-x] -A arch -O os -T type -C comp -a
addr -e ep -n name -d data_file[:data_file...] image
-A ==> set architecture to 'arch'
-O ==> set operating system to 'os'
-T ==> set image type to 'type'
-C ==> set compression type 'comp'
-a ==> set load address to 'addr' (hex)
-e ==> set entry point to 'ep' (hex)
-n ==> set image name to 'name'
-d ==> use image data from 'datafile'
-x ==> set XIP (execute in place)
make: *** [arch/blackfin/boot/uImage.lzma] Error 1
May be unrelated, though.

when I'm talking to journalists I just say "programmer" or something like that.
