LLVM has complicated static library layering that sometimes changes. The make solution was to list all the static libraries twice, but Soong dedups the list. Add a group_static_libs flag to allow surrounding the static libs with -Wl,--start-group and -Wl,--end-group. Test: mmma -j external/llvm Change-Id: Ic08a183d7def9c9249d4a3014760759f16b68d04
