Nick Clifton 0013291dce When looking for a previously loaded file compare the local_sym_name not the
filename, as the filename might have been transformed via the search directory
path lookup.  If the sought-for file has not been found in the input file
chain then create a new node with the search_dirs_flag set so that the entire
set of directory paths will be scanned for it.
