Retire build support for GCC's DWARF unwinder

As of r356514 LLVM's libunwind is used as the DWARF unwinder on all
supported CPU architectures, and GCC and its libraries will be removed
soon.  Retire the build infrastructure for GCC's unwinder; from here
if there are any unwinder bugs (on any arch) the path forward is to fix
LLVM's libunwind.
