dbghelp: Implement fetch_thread_info on powerpc to allow wine to be built on ppc. [resent2]

[Pierre d'Herbemont]

Hi,

We need this patch to build Wine on PowerPC.

(sorry for the spam, previous patch was broken, and I've just noticed  
that rpc fix is not needed now.)

Thanks,

Pierre.

ChangeLog:
Implement fetch_thread_info on powerpc.
