Migrated dejagnu testcases and support files for testing nm to gdb/testsuite from deja-gnu. These files were moved "as is" with no modifications. This migration is part of a major overhaul of dejagnu. The modifications to these testcases, etc., which will allow them to work with the new version of dejagnu will be made in a future update.
