RFC PATCH 1/1 libunwind: Build with gold to avoid build failures

The library fails to build with binutils 2.25 and standard ld. This issue is fixed in gcc 5 with no plans to backport to gcc 4. Easiest workaround for now is to use gold as the linker for the library since gold does not have the issue. The bug is x86 only.
