Comment:
The way you have it set up, make doesn't run in `do_build()` when native compiling.
The object files getting compiled `do_install()` is not correct as the variables set when running `do_install()` are not necessarily the same as with `do_build()`.

You don't need to use a custom `do_build()` here, there is a variable `make_build_args` for this purpose, although as Duncaen said, the correct fix is to remove the CC assignment in the makefile so that the compiler can be specified by the environment.
