bug#5492: 23.1.91; Building Emacs triggers warning about charsets directory

[Eli Zaretskii <eliz@gnu.org>]

During compilation of files.el, in a tree that was not yet installed, I
get the following message:

    Compiling /home/e/eliz/bzr/emacs/trunk/src/../lisp/files.el
    Warning: arch-independent data dir (/usr/local/share/emacs/23.1.91/etc/)
    does not exist.
    Error: charsets directory (/usr/local/share/emacs/23.1.91/etc/charsets)
    does not exist.
    Emacs will not function correctly without the character map files.
    Please check your installation!

I think this warning should be suppressed in an un-installed
Emacs.  At the very least, it should be a "Warning", not an "Error".
For best results, we should look at the charsets directory in the build
tree in this case.
