As slightly discussed with Mark, there are tests that expect 'main'
will be present in backtrace. That's not always true on x86_64 because
-freorder-blocks-and-partition option is on by default. Then one can see:

[   88s] FAIL: run-backtrace-dwarf.sh

Thus I'm suggesting to disable the option for tests?
