389211 – sys-kernel/gentoo-sources - deblob fails with python-3

When emerging a kernel with deblob support enabled while using python-3, the deblobbing process fails but continues which can lead to a kernel build failure:

DVB_AV7110 - AV7110 cards
drivers/media/dvb/ttpci/av7110.c: disabled non-Free firmware-loading machinery
  File "/var/tmp/portage/sys-kernel/gentoo-sources-3.0.6/temp/deblob-check-script-q4yNnF", line 74
    print 'looking for matches'
                              ^
SyntaxError: invalid syntax

This is fixed from deblob-3.1, but broken for all previous versions.
