Comment (by kencu):

 Actually Jonathan, because you have a relatively untouched system there,
 would you like to try that fix?

 Just edit the libcxx Portfile, remove ppc from the supported archs, save
 that file, and then try your installation of squid4 again.

 If we are lucky, it will just build clang-7.0 as non-universal, and libcxx
 as non-universal, and we might be done there.
