Hi,

GDB currently dlopen()s `libunwind-ia64.so':
	#define LIBUNWIND_SO "libunwind-" STRINGIFY(UNW_TARGET) ".so"

and uses its symbol in a defined ABI way afterwards.
This makes an incompatible ABI change impossible.

`libunwind-ia64.so' should be used only for the build time while runtime should
use `libunwind-ia64.so.7' in this case.

libunwind author's approval:
