gdb 5.0 m68k bug remains???

[Joel Sherrill]

Eric Valette has updated the Ethernet remote debugging support for
RTEMS to gdb 5.0 and I am merging the other parts of the gdb 4.18
patch.  I have come across this small patch that I think
still needs to be applied but wanted feedback before discarding it.

Feedback welcomed.
