A few more thoughts:

quiet_cmd_bzip2 = BZIP2    $@
cmd_bzip2 = (bzip2 -9 < $< ; $(size_append) $<) > $@

quiet_cmd_lzma = LZMA    $@
cmd_lzma = (lzma -9 -c $< ; $(size_append) $<) >$@

These will produce stale files on failure.  Using stdout in Makefiles is 
a bit tricky.  You probably need something like:

(bzip2 -9 < $<  && $(size_append) $<) > $@ || (rm -f $@ ; false)
