Matheus Tavares Bernardino 3128588232 Hexagon: append eflags to unknown cpu model string
Running qemu-hexagon with a binary that was compiled for an arch version
unknown by qemu can produce a somewhat confusing message:

  qemu-hexagon: unable to find CPU model 'unknown'

Let's give a bit more info by appending the eflags so that the message
becomes:

  qemu-hexagon: unable to find CPU model 'unknown (0x69)'
