Fix FreeBSD aarch64 faulies when use luajit 

* FreeBSD uses lld, and lld does not support -Ttext-segment,
  suggesting --image-base instead. Not sure if it's equivalent change
  for the purpose at least if fixes build on FreeBSD/aarch64.
  Note that the code checks for FreeBSD, while it should really check
  for lld on any system, however I don't know any CMake facilities which allow this
