When using full LTO on cross-compile settings, instead of generating the
default archive kind of the host platform, we could deduce the archive
kind based on the target triple.

This specifically addresses https://github.com/android/ndk/issues/1209
by making it possible to drop llvm-ar in place of GNU ar without extra
flags.
