glibc: Enable memory tagging for aarch64
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.
