I think you perfectly answered your own question. Performing a test
build under sbuild or pbuilder and looking at which compiler is being
used is a good approach to answer it. There isn't anything more to it.
Your own analysis clearly says that exporting CC is no longer necessary.

I'm also happy that apparently cross building using pbuilder is no
longer too hard for the uninitiated. Good work, Mattia! :)
