[Qemu-devel] [PATCH 12/13] target-openrisc: Add correct gdb information for the pc value

[Sebastian Macke <sebastian@macke.de>]

The former patch which removed npc and ppc also removed the part in
which the registers were send to gdb. But the npc parameter
is necessary and the numbering of registers is fixed within gdb.
The correct npc value is the current pc value.
