[PATCH] AArch64: Add command line option to select big or little endian

[Christian Pirker]

  Hi All,

  I made already a similar path for ARM targets (D3307).

  As written by Scott, he would prefer it as it is, with the -EB/-EL tests removed.
  I think we can leave these tests in.
  So would it be accepted to commit this patch (with all test cases)?

  Thanks,
  Christian
