LinuxBionic now supports arm64 architecture in addition to the existing x86_64 arch. This is to make it possible to build host tools like adb, fastboot, crosvm, etc. for Linux/ARM on regular Linux/x86 machines. The arm64 target can be selected in various ways in Android.bp files: - target.host (because this is still considered as a host target) - target.linux (provided that the module is also enabled for host) - target.linux_bionic (use the OS name directly) - target.linux_bionic_arm64 (OS name + arch combo) - target.linux_arm64 (provided that the module is also for host) - target.not_windows - arch.arm64 The toolchain for the new target is almost the same as the toolchain config for Android/ARM64. One notable difference is that the clang triple is aarch64-linux instead of aarch64-linux-android, so that __ANDROID__ is not defined for the new OS type.
