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.
Also, get rid of the temp file: dtc accepts "-" for stdin.
