Drastically simplified by taking advantage of the "install" command's

new flexibility, specifically the 'root' option.  Now, we just use
"install" to do a fake installation into a temporary directory
(the 'bdist_dir' option, which derives from the 'bdist_base' option of
"bdist"), and then tar/zip up that directory.  This means that dumb
built distributions are now relative to the root directory, rather than
the prefix or exec-prefix; this is probably a feature, but does make
them slightly less flexible.
