Address libunwind.a inconsistency issues in the bootstrap program

We noticed when building rustc multiple time in a roll, some files will not be consistent across the build despite the fact that they are built from same source under the same environment. This patch addresses the inconsistency issue we found on libunwind.a, by sorting the order of the files passed to the linker.
