On powerpc64--linux, annota1.exp has two problems:

1) A breakpoint in a shared object may be 'delayed'.  This changes GDB's 
responce: both when the breakpoint is set and when it is hit.

2) Due to a bug (I which I knew the number), GDB 'skids' past the top-of-stack 
when doing a backtrace.  This causes two extra and severial garbage stack 
frames to be displayed, eventually getting an error.

I have attached three patches: seperate patches for these two problems and one 
patch that fixes them both.  I have also attached test logs so you can see 
what's up.

Ok to commit? (which one(s)?)

PS:  I thought the 'skidding past top-of-stack' problem was fixed.  But it 
doesn't seem to be in cvs-main as of last week sometime.
