message: Workaround Xcode 10.2 release build crash
  The linker crashes when linking PoeditQuicklook.qlgenerator (but
  strangely, not the main binary) with
  clang: error: unable to execute command: Bus error: 10
  clang: error: linker command failed due to signal (use -v to see invocation)
  Workaround by changing LTO from incremental to full.
