This used to work because we used to pass -e to every make:

       -e, --environment-overrides
            Give variables taken from the environment precedence over
variables from makefiles.

So the exported CC=my-cross-gcc in bitbake.conf overrode the CC assignment
in the Makefile.

This is a vile hack though so we don't do itnow.  You'll just need to set
CC etc when calling make, trivially done with EXTRA_OEMAKE.

In fact this is even in the documentation:
