On baremetal machine, as you suspected opt entir line(a preprocess command invoked by lllc-update python script) is creating problem, as it is entirely executed as it is on terminal, thus unable to locate opt binary path, as in case of llc tool!
I handled it, by letting hardcoding the opt path, followed by updating it via script & reverting the opt path back to original as was in test. But, in future it would be a problem if someone else tries to run update-llc script again & need to again do the same hack as I did now!
