Lisp file permissions after install

[Chong Yidong]

As an unprivileged user, I run ./configure and make on the Emacs
sources. After the compilation is done, I su to root and make install.

The .el and .elc files copied into /usr/local/share/emacs/21.1.x are
then owned by the unprivileged user. I think this is a mistake, as the
/usr/local/share tree should be read-only for unprivileged users. The
other files installed by Emacs (in /usr/local/bin, /usr/local/libexec,
and so forth) have correct permissions.

I am not familiar with the build process. Would it be possible to
perform chown and chgrp on the lisp files, whenever the install
destination is owned by root?
