Normally, the debug build of some software would (i) generate better
diagnostics (at the cost of possible information leaks log volume
problems) and (ii) add additional checks to the code which will detect
more bugs (at the a possible performance cost).

osstest doesn't do much perf testing and the other downsides aren't
relevant.
