  In ldfile_open_command_file_1() name written to the dependency files is
the name as specified passed to the "INCLUDE" directive.
This is before include-path processing so the tracked dependency
location is most likely wrong.

Instead track the opened file at the point where the full path is
actually available, in ldfile_find_command_file().

This patch is incomplete.  ldfile_find_command_file possibly opens a
file in two places.
