gdb+qemu+rtems: Problem #2 in offset computation

[Joel Sherrill]

There are (were) five reasons the timer calibation could fail on pc386. It did appear to happen in qemu and not on real hardware and in qemu inside a vm more than just qemu. It is something to do with the simulated timer jumping.  I doubt changing the amount of memory helps. It is rather random. Run again and it may not happen.

FWIW I committed a fix to the head where if it hits this situation, it will retry five times before locking up. Should help. Maybe I should apply this to the release branches.
