This ELF note is aarch64 and Android-specific. It specifies to the dynamic loader that specific work should be scheduled to enable MTE protection of stack and heap regions. Current synthesis of the ".note.android.memtag" ELF note is done in the Android build system. We'd like to move that to the compiler, and this is the first step.
