 Xamarin.Android uses a handful of utilities from LLVM (`llvm-mc`
-assembler and `llvm-strip/objcopy`), the `gold` linker from GNU
-Binutils and a custom wrapper for `llvm-mc` which implements the GNU
-AS interface required by Mono AOT and Xamarin.Android alike. These
-utilities are used in Xamarin.Android application build process, parts
-of which entail generation of native assembly for `ARM`, `ARM64`,
