PATCH: Fix ARM "open" simulation

[Andrew Cagney]

Mark,

You're not listed as write-after-approval in GDB's MAINTAINERS file and 
that is ment to be a pre-req to being able to commit changes to GDB. 
Per the MAINTAINERS file, people get added to that once their assignment 
status for GCC has been confirmed and they have contributed a good patch 
(I see CodeSourcery has a blanket assignment, and the patch is I guess ok).

Can you please add yourself to GDB's write-after-approval list (don't 
forget the changelog and to post the change).

enjoy,
Andrew
