They get autodeleted after the runtargets are run..

[Pehraps we should switch the default to not autoremove - and use an
extra option to do this autodelete?]

Also - I see the binaries are autodeleted - but not .o files.  [but
they don't take much space as compared to other stuff we now keep -
like the .o files for the sourcefiles]
