* I dropped the compiler choices
* BCLANG/PCLANG - this required a dependency on an old llvm37
* So for now, just `USE_GCC` always
[note, with some changes to compiler/main/*hs we could maybe get it to work with base clang as compiler]-
* Use `SUB_FILES` to create the `build.mk` file
* Prepare a target to create future bootstrap tarballs
* Note, I did not yet add the SUBDIR += entries for the new ports or add MOVED entries for hs-directory.
