Can we restructure build system a bit to generate separate
"ghcconfig.h" for all the stages we are trying to build?
It would mean generating two local "ghcconfig.h" files and
make them available at once:

- which are equal to booter compiler in native case
- differ from host compiler where in case --target=T (--host=--build=H)
  stage1's:
    #define BuildPlatform_TYPE  H
    #define HostPlatform_TYPE  H
    #define TargetPlatform_TYPE T
  stage2's:
    #define BuildPlatform_TYPE  H
    #define HostPlatform_TYPE  T
    #define TargetPlatform_TYPE T

Thanks!
