PATCH 1/1 Handle debug signals on PowerPC

Hi,

The attached patch allows PowerPC QEMU to be used with the debugger.

Currently, any attempt to debug causes an unknown exception error. Note that there are also a few other issues that prevent QEMU from working at all (for me, at any rate, and not just with debugging), but those fixes are not yet ready.

Actually POWERPC_EXCP_DEBUG can not happen in user mode, while EXCP_DEBUG should be handled. The mistake come from a renaming of all PowerPC EXCP_* defines into POWERPC_EXCP_*.

I have applied a patch to fix that.
