Fix arguments passed to llvm-readobj
Upstream llvm-readobj no longer accepts single dash prefix for long options. Changed to double dash. Also let the script to raise exception if rc is non-zero, to avoid getting confusing error later in the program. Test: build Bug: 197230471 Change-Id: I364f51322904431d430549f79af58f455f47e028
