[vta/trunk?] add --preserve flag to contrib/compare-debug

It's sometimes useful to look at the stripped object files that
compare-debug creates, when you don't want to be distracted by changes
to the debug information.  This patch introduces a flag that permits
compare-debug to retain the stripped object files.

I'm installing it in the vta branch.  Does anyone oppose my installing
it in the trunk, when I return from a trip later this week?
