Before checking in the patch, i figured out the rest of the problems.

Newer GDB's seem to have fixed a problem with displaying thunks in the 
virtual tables. Older ones did not demangle those names properly.

With that said, ppc64 uses dot symbols for those thunks, so we need to 
account for those in the testcase as well.

Here's the updated patch. I escaped dot once (\.) instead of twice. So 
hopefully this is the correct way. I often get confused with escaping in 
dejagnu.

With this fix, i see only a single failure for virtfunc.exp on ppc64. 
The other failure is more involved and i'm still chasing the root cause.

	* gdb.cp/virtfunc.exp (make_one_vtable_result): Handle extra output
	from targets that use function descriptors in the virtual tables.
	Handle presence of dot symbols.
