Subject: [PATCH] Patch from David Mosberger * 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.
