[AArch64] Remove all traces of aarch64-without-fpu.xml.

Browse source 
The aarch64-without-fpu description is unused.

Linux requires an FPU, so the AArch64 native port always returns the
with-fpu variant:

static const struct target_desc *
aarch64_linux_read_description (struct target_ops *ops)
{
  initialize_tdesc_aarch64 ();
  return tdesc_aarch64;
}

When the target doesn't report a target description at all, we
fallback to a register set with an FPU:

aarch64_gdbarch_init ()
...
  if (!tdesc_has_registers (tdesc))
    tdesc = tdesc_aarch64;

This just removes the dead description.

Tested by building on x86_64 Fedora 17 with --enable=targets=all.
