(NickC worded this very well)

I'm wondering if it would be helpful for sim specific maintainers (at 
least for sim/common based sims) to have implicit approval/write 
permission on the sim/common directory.

Which reminds me, Stephane Carrez should really be listed as the m68hc11 
maintainer.  Unless, that is, GDB is going to assume that a GDB target 
maintainer implicitly maintains the corresponding SIM.

Thoughts?
