Before clang 16, the libunwind install only contained the libunwind.a library. Since clang 16, however, it also contains header files, including a unwind.h file that conflicts with the unwind.h file that is also shipped alongside compiler-rt. When building clang itself with compiler-rt and libunwind (i.e. not building everything separately like we do), however, that's not a problem because it puts libunwind in a different directory than compiler-rt. So we change the clang repacking to follow a similar convention. But because clang doesn't look for libraries under clang/lib/$arch, but looks under clang/lib/$target instead, we also need to enable per-target directories for libunwind. But because clang also looks for libraries under clang/lib/$exact_target rather than clang/lib/$relaxed_target (in Android's case, exact_target might be aarch64-unknown-linux-android21, relaxed_target aarch64-unknown-linux-android), we patch clang to apply the same kind of fallbacks it does for runtimes for clang/lib.
