Add @var{file} to the list of files that @value{GDBN} will search for

debug information for the objfile.

This is useful when the debug info has been removed from the program

and stored in a separate file. @value{GDBN} has built-in support for

finding separate debug info files (@pxref{Separate Debug Files}), but if
