I don't fully understand what's going on in your case, but could you try
removing the "CC=" line from the makefile? 'Cause it's the whole point
of scan-build that it injects the analyzer through CC, so it can't work
if you immediately overwrite it back. I think normally makefiles only
enforce their own CC if it's unset otherwise.
