GDB 6.5 RTEMS patch

Hi,

Attached is the patch we are using with gdb 6.5 for RTEMS.
It is essentially the same patch we used with 6.4. It
primarily enables the erc32 simulator for sparc-rtems
and makes it compile. There were a couple of minor
Makefile glitches fixed to make packaging with RPM
work for us. It is one patch but touches code in
3 directories with ChangeLogs. 

I am not subscribed to this list so please cc me on
any replies.

Thanks.
