The work loop relies on the compiler not optimizing it away, although
named_threads_work is not static for that reason, the compiler could
still do it.
Fix it by compiling without optimization. Also add -fno-inline for
consistency and in case anyone wants to look at callstacks.
Fixes: b5dd510be55e8670 ("perf test: Add named_threads workload")
Closes: https://lore.kernel.org/all/20260609160001.2739E1F00893@smtp.kernel.org
