To that effect ports also need to respect CC/CXX. There were a few -exp
runs without /usr/bin/{cc,gcc,etc} to find out non-conforming ones as
part of ports/159117. However, the issue was quickly shoved under the
carpet in order to focus on the more important, clang as default.

Ignoring for the moment clang -exp runs are *still* done with clang 3.0
while we're discussing here clang 3.2 becoming default.
