Hi Wolfgang,

Current versions of dtc always print a message like
DTC: dts->dtb on file "dt.dtb.tmp"
which cannot even be suppressed with "-qqq". To avoid incorrect MAKEALL status, we manually filter out this message. This is a bit complicated, as we have to make sure to set a correct return code.
See the discussion on this patch:
http://patchwork.ozlabs.org/patch/149833/
A patch to fix this has now been accepted to dtc. So if you update dtc you should find this message goes away.
3cbf829 dtc: Remove spurious output on stderr
Also, get rid of the temp file: dtc accepts "-" for stdin.
