The perf binary I built was referring to /lib64/, from
elfutils-0.157, rather than /opt/libdw/lib/ from my build.

I got a workaround for the 'yum update' problem[1]. With elfutils-0.158
the eu-stack and perf seem to work better.

BTW, I did not find 'eu-stack' in elfutils-0.157; I got the NO_UNWIND
error with '/opt/libdw/bin/stack -p $$' and that binary was also referring
to from 0.157.

Thank you,
