yeah, but we're depending upon a host tool that isn't documented.
we tend to try to fix those, espcially for the reasons like above.
if some host sort(1) has a different output to what we expect then
it's not good enough, and there's nothing to stop this happening
afaict.  eg, we have TOOL_SED and TOOL_AWK now...

i'm not saying we _should_ do this, but more asking if others have
opinions on it.  i'm not sure we should only fix the build issues
we see bugs for -- future sort uses might be added that don't break
normal builds, but do others, unless we future proof sort usage..
