The only thing testsuite_{thread,wchar_t} are used for is from 
create_testuite_files.  Not the *use* of testsuite_files, but the script 
that is used to create testsuite_files.  So, if you're in the habit of 
creating testsuite_files by hand (to run a few tests), then we could 
still remove create_testsuite_files and testsuite_{thread,wchar_t}. 
But, if you're using create_testsuite_files to create testsuite_files, 
then we should keep the files around so that the create_testsuite_files 
script works correctly.
