works ok until building glibc with the just built
compiler. _Unwind_Resume, _Unwind_GetRegionStart are referenced by
glibc objects, _Unwind_GetIP, _Unwind_SetGR, _Unwind_SetGR,
_Unwind_SetIP are referenced by libgcc_eh.a. Found in the standalone
libunwind.a:

0000000000000000 g     F .text  0000000000000060 .protected _Unwind_GetRegionStart
0000000000000000         *UND*  0000000000000000 _ULia64_get_proc_info
0000000000000000 g     F .text  0000000000000060 __libunwind_Unwind_GetRegionStart

a quick fix is to undefine the PROTECTED macro in unwind-0.98.3,
surely not the right thing to do?
