Cygwin-related changes.

- Disabled check for secure temporary directories under Cygwin
- objc-load.m codepaths used for MinGW are now also used for Cygwin. Even in
  case of some functionality that should be standard under UNIX systems, it
  turns out that this functionality is, sadly, not present under Cygwin (e.g.
  dladdr()).
