I don’t like to add override-name and override-version flags.  They
don’t seem very useful.  After all, every different build gets its own
directory in the store, so “override-version” seems to be useless.

“override-name” just duplicates the package name, so I fail to see how
it would be an improvement.

I do agree that it would be a little nicer if we could build and install
a package from a directory, rather than just from a tarball.
