[RFC PATCH 13/13] of: Remove unused variable overlay_symbols

[frowand . list]

From: Frank Rowand <frank.rowand@xxxxxxxxxxx>

This unused variable is a reminder that symbols in overlays are
not available to subsequent overlays.  If such a feature is
desired then there are several ways it could be implemented.
