PATCH [1/4] C-SKY port V3: ELF and BFD support

[Andrew Jenner <andrew at codesourcery dot com>]

Here's part 1 of the C-SKY port, covering the ELF and BFD support.

One technical note on this patch part:  the C-SKY port historically used 
the same value for EM_CSKY that was originally assigned to EM_MCORE 
(39), which caused various conflicts unless EM_MCORE was disabled. We've 
gotten a new official number assigned for EM_CSKY but continue to 
recognize objects using EM_MCORE for backward compatibility.  (Some 
other ports also have similar code to deal with old unofficial EM_xxx 
numbers.)
