Hi Petr,

Why do you need the duplicate .needs_cmds flag?(it introduces the double 
check as you said)

Usually, all tests run commands by tst_run_cmd()/SAFE_RUN_CMD() and they 
can report TCONF

by passing TST_RUN_CMD_CHECK_CMD so it is fair to be a part of 
tst_run_cmd()/SAFE_RUN_CMD().

Thanks,

Xiao Yang
