To keep existing targets, in case somebody use them.

Right, not fully compatible, but still can do:
make examples / make examples_clean
make examples T=x86_64-native-linuxapp-gcc

Overall, if you believe keeping them is confusing, I am OK with it, just
may need to update doc/build-sdk-quick.txt to fix "make help" output.
