That's a good question. I don't have a strong opinion myself, so I
tend to trust larger projects like Linux to have thought this through
more, and they use 'CC = cc' as well. So I'd lean toward the updating
'ci/' scripts approach, to do something like
make ${CC:+"CC=$CC"} ...
(or the equivalent multi-line construction).
That also has the bonus of being explicit.
Just my two cents,
Jonathan
