arch-test binary package in Ubuntu Focal amd64

 This package lets you enumerate architectures that your kernel can run.
 The check is for the ability to run machine code and supporting appropriate
 syscall ABI -- you may need to install userland libraries in a chroot,
 container or via multiarch to actually execute non-static binaries of such
 architectures.
 .
 Also provided is "elf-arch", a tool to determine the architecture of an ELF
 binary (program or library).
 .
 Architectures detected by this version of arch-test are:
  * amd64, i386, x32
  * mips, mipsel, mips64, mips64el
  * arm, armel, armhf, arm64, arm64ilp32
  * powerpc, ppc64, ppc64el, powerpcspe
  * m68k
  * sh4
  * s390x
