ANDROID: Kbuild, LLVMLinux: allow overriding clang target triple Android has an unusual setup where the kernel needs to target [arch]-linux-gnu to avoid Android userspace-specific flags and optimizations, but AOSP doesn't ship a matching binutils. Add a new variable CLANG_TRIPLE which can override the "-target" triple used to compile the kernel, while using a different CROSS_COMPILE to pick the binutils/gcc installation. For Android you'd do something like: export CLANG_TRIPLE=aarch64-linux-gnu- export CROSS_COMPILE=aarch64-linux-android- If you don't need something like this, leave CLANG_TRIPLE unset and it will default to CROSS_COMPILE.
