Add to that
- TARGET_BASE_ARCH in Makefile.target is assumed to be the name of the
target-* subdirectory, but this will not always be desirable.

For a long time already I have been carrying the following patch
Still need to rebase that, but it looks as if there are no conflicts
with your series.
TARGET_NAME while a bit invasive is certainly nicer than TARGET_ARCH2,
and dropping TargetType enum makes rebasing/adding new targets easier.
