Romain Naour 3bc94471ca support/docker: prepare for Aarch64 Docker images ...

With the new 'buildx' command using 'BuildKit' since Docker 23.0 [1],
it become easy to build the same image for several architectures [2].
The only requirement is to use a Dockerfile without any architecture
specific definition.

Since our current Dockefile contains already some i386 specific
packages (g++-multilib,libc6:i386) to provide x86 32bits support,
we have to install them conditionally.

Update the build process described in the Dockerfile accordingly.

For now, Aarch64 hosts can't be used by the Buildroot testsuite (yet)
since the Bootlin external toolchain (used by default) currently only
support x86_64 hosts.
