versioned files in DESTDIR breaking build

[Greg Troxel <gdt%ir.bbn.com@localhost>]

I do update builds usually, and occasionally have to remove stale files.
But, it seems like every week I have the following problem, and I wonder
if it should be part of build.sh to clean this out.  Or perhaps, to have
update not clean the obj dirs but always use a fresh destdir.
