CC: Mark Wielaard <mark@klomp.org>
This patch add backend support for C-SKY architecture.
FAIL cases on csky:
1. run-backtrace-*
discussed in this thread before, seems can't support with current
core_set_initial_registers.

test binary:
https://github.com/c-sky/test-result/blob/master/elfutils/divzero
https://github.com/c-sky/test-result/blob/master/elfutils/core
2. run-native-test.sh
ssh script problem, can pass if it is ran directly.
3. run-dwarf-getmacros.sh
ssh script problem, the empty string argument is lose,
can pass if it is ran directly.
4. run-deleted.sh
ssh script problem, can pass if it is ran directly.
5. run-reverse-sections-self.sh
elfcopy --reverse-offs dose not work properly on C-SKY object file,
seems not related to arch specific code.
