Fixed kernel test cross compile after upgrade to flatbuffers 2.0.6

robert-kalmar · robert-kalmar · commit d1a4dd836af3 · 2022-08-23T13:58:12.000+02:00
Flatbuffers 2.0.6 attempts to generate files with built flatc compiler,
if Python3 interpretter is available. At crosscompilation, this compiler
is build for target archtitecture hence not working on host.
This change suppress the file generation.
