Huh, we use in a lot of places.

I agree. My opinion is that setting CC and CXX correctly for his setup
is in theory the basic setting and if that is what the developer wants
to do, it is all that should be needed. No --with-this-sdk or
--with-that-ndk style options should be needed if CC and CXX by
themselves cover all that.

But yeah, I agree that you then must know what you are doing and what
more or less obscure options to include in CC/CXX. It is easier to
only specify what SDK/NDK version (and/or the path to it) to build
against.
