Doubt it. From 'info make', Node: Environment.

Variables in `make' can come from the environment in which `make' is
run. Every environment variable that `make' sees when it starts up
is transformed into a `make' variable with the same name and value.
But an explicit assignment in the makefile, or with a command
argument, overrides the environment. (If the `-e' flag is specified,
then values from the environment override assignments in the
makefile. *Note Summary of Options: Options Summary. But this is
not recommended practice.)

The kernel Makefile explicitly sets CC which overrides the environment
value, but does not override a command line definition of CC. IOW, do
not reply on environment variables always working with make.
