001b1cf010 build: use standard branch-protection for aarch64-linux (fanquake)

Pull request description:

  Use `-mbranch-protection=standard` when targetting `*aarch64-*-linux*`.
  Part of #24123, but this flag can already be used on a best effort basis.

  Note that this flag is also already used by default, in the toolchain, on various distros (i.e Fedora).
