Comment (by kencu):

 It probably goes to `/usr/bin/c++` because it doesn't have anything on the
 fallback list that is not blacklisted to choose.
 {{{
 :warn:configure All compilers are either blacklisted or unavailable;
 defaulting to first fallback option
 :debug:configure Environment:
 :debug:configure CC='/usr/bin/cc'
