Comment (by barracuda156):

 Replying to [comment:3 jmroot]:
 > OK, so it's the fact that clang is used with build_arch=ppc that you're
 concerned about. The decision whether to put clang or gcc first in the
 fallback list is based on `${configure.build_arch}`, which is empty for
 noarch ports.

 Yeah, it essentially breaks those ports for PPC, unless
 `configure.compiler=` is passed on command line, which is not something
 obvious. And things get worse when some dependency of a port has this
 problem.
