Log Message:
Begin adding some of the basic, non-intrusive pieces of the
cross-compile support.

- NATIVE_MACHINE_GNU_ARCH, NATIVE_LOWER_ARCH, NATIVE_MACHINE_ARCH,
  NATIVE_MACHINE_PLATFORM and NATIVE_MACHINE_GNU_PLATFORM work
  like the counterpars without NATIVE_ prefix. Expansion of
  NATIVE_LOWER_ARCH and NATIVE_MACHINE_ARCH is enforced early,
  so that MACHINE_ARCH can be overriden in mk.conf to specify the
  target architecture.
- Provide a default of NO for USE_CROSS_COMPILE. This will be the
  main switch to activate cross-compiling and adding it now makes
  it possible to merge more of the patches for specific packages.
- Set --build and --host when cross-compiling, the former using the
  just added variable NATIVE_MACHINE_GNU_PLATFORM.
