  * FIX #1845 (unconditional relative branch out of range)
  
  Don't use mmap on powerpc-apple-darwin as mmap doesn't support
  reallocating but we need to allocate jump islands just after each
  object images. Otherwise relative branches to jump islands can fail
  due to 24-bits displacement overflow.

    M ./rts/Linker.c -1 +12
