Target deprecation, round three

[Zack Weinberg]

So let me get this straight, you are proposing the removal of

   mips64orion-*-rtems*
   sh-*-rtems* # COFF only
   v850-*-rtems*

in addition to what's already on my list (which includes i960-*-rtems*)?

Does it make sense to keep mips64orion*-*-elf* if RTEMS is gone?
