Hi,

When installing Gnus, specifying no options, a lot of Lisp files
will be scattered underneath the site-lisp directory.  I considered
over ten years that it's not a good idea.  In addition to this,
there's another problem that ``./configure; make install'' will
never install .el files.  WDYT?

I made a patch for both of them.  I think a similar change should
also be applied to the v5-10 branch.
