It may take a while but realistically the only people who care about the
sparc simulator are RTEMS folks and AdaCore. And you are certainly
to be trusted for the patches.

Submit them.  And help the RSB switch to using all the newer patches.
Then we can get some test time on them. That's what the gdb folks
will want to hear.

We can move rtems sparc GDB to whereever it needs to be but the
gdb head is better for submissions and we should base the RSB
version on a release.
