gdb stub initialization order

Hello Paul,

I have recently contributed a generic (?) m68k-
gdb stub suitable for RTEMS aswell as an adaption 
layer between ther standard stub I/O functions 
and RTEMS termios-polled drivers. This adaption 
layer should work with any serial driver 
supporting the polled termios model and it is 
configured in the "Init" module in a similar way 
as other RTEMS configuration options. Its 
initialization code is called from "post-driver-
hook", just the same location you mentioned. It 
has been tested for MC68040 and MC68360 boards. 
The adaption layer "serdbg" and the m68k-stub is 
available with the latest snapshots, but should 
in general work also with 4.5.0.

Hope this helps!
