Oh, two other things.  I liked Frank's suggestion:

  Or alternately, could the "asneeded" setting stay as it is, but extend
  gdb's backtrace command to have a sufficiently non-symbolic mode,
  where the "asneeded" data would not be needed and thus not loaded?

And I don't think we need a command line option for this.  Would a
"set" be enough?  You're going to have to feed a command file to GDB
anyway to get the backtrace.
