[PATCH v2 2/4] add standard_temp_file

[Tom Tromey <tromey@redhat.com>]

This adds a new helper proc, standard_temp_file.  This proc takes a
file name and returns a possibly-qualified form.  This lets us make
parallel runs use a directory other than ".", which helps the inotify
mode.

This initial patch just introduces the proc.

	* lib/gdb.exp (standard_temp_file): New proc.
