[patch 2.6.11-rc5] Add target debug_kallsyms

[Keith Owens]

Make it easier to generate maps for debugging kallsyms problems.
debug_kallsyms is only a debugging target so no help or silent mode.

Applied to my kbuild tree.
I will remove it when we stop see kallsyms reports.

Good luck!  Most of the kallsyms reports are not really kallsyms bugs,
rather they are caused by the kallsyms checking picking up toolchain
problems.
