I’d personally find it more than a little odd to have a setting in /etc/make.conf in conjunction with a build create side-effects in my filesystem such that this behavior results:

# cc -v
Using built-in specs.
Target: amd64-undermydesk-freebsd
…
# cd /usr/src; make buildworld
# cc -v
FreeBSD clang version 3.3 (tags/RELEASE_33/final 183502) 20130610
..

In other words, a build that was formerly not mutagenic to the build system now becomes mutagenic, unless you had some other value of “cc” in mind than /usr/bin/cc?

Why not simply follow existing precedent and introduce a cc-select command that sets up all of the appropriate symlinks?  Then at least rather than setting a DEFAULT_COMPILER in /etc/make.conf you just run the command explicitly to change the default compiler and there are no surprises, since you did it explicitly.
