The build may succeed but if the native GCC compiler was picked, then
it's a native build and not a cross-build. You can run the following
command:

--8<---------------cut here---------------start------------->8---
file the-binary-or-library
--8<---------------cut here---------------end--------------->8---

and see what it reports. You can also have a look to maradns package
for an example of how to deal with CC variable.

Don't hesitate if you have further questions,
