Glibc on aarch64 has a memory tagging option that can be enabled via GLIBC_TUNABLES="glibc.mem.tagging=$SOMETHING" when glibc is built with memory tagging support and the kernel/HW supports MTE. There should be no side effects unless the user turns it on with approprate HW support Linux 5.4 headers and binutils 2.33.1 or newer is needed.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
