* Top level makefile: Fixed and simplified cross-building. It is now possible to perform cross builds when having only bootstrap compiler executable.

- Always use fresh native fpcmake executable.
  - Build fresh native fpcmake executable when cross-compiling.
  - Explicitly specify a compiler which is used to bootstrap fpmake and fpcmake. Always use fresh native compiler for that. 
* New bootstrap target for fpcmake to build native fpcmake regardless of CPU/OS settings.
