gdb support for Linux vsyscall DSO

[Andrew Cagney]

Roland,

There is no silver bullet.

However, there are designs that [I think] provide both GDB and the 
kernel the best of possible worlds.  If the kernel simply dumps out its 
raw information (instead of cooking it in a way it thinks will be useful 
to debuggers) then GDB can pick and choose what it really needs.  This 
also means that the core file and live process are both furnishing GDB 
with identical data.  Might even make the kernel cleaner.
