* config/t-libunwind: Mention unwind-c.c.
(SHLIB_LC): Overwrite the default-value from t-slibgcc-elf-ver
and mention -lunwind so that the resulting libgcc_s.so has
the necessary DT_NEEDED entry for libunwind.
* unwind-libunwind.c (_Unwind_GetCFA): Implement.
(_Unwind_GetBSP) [UNW_TARGET_IA64]: New function.
