Well, Chris, for better or worst, this "feature" does seem to work.  I
did a quick test of this using an @file which is 81k long and it works!
You will need to remount both /usr/bin and /usr/lib with the "--system
--binary -X" options.  Then put your list of objects into @file and run
gcc @file.
For the record, I still feel that a better practice is to do archiving of
object files and link with the library, but if this gets you going, this
time, more power to ya.
