Bro failing to build on OS X with XCode 7

I can’t get Bro master to build with XCode 7 on OS X. For anyone trying to build Bro on a new OS X system, this is a problem, since I don’t think old versions of XCode are still available.

$ cc -v

Any ideas on how to fix this? This seems related: https://github.com/bro/binpac/commit/e42a18d8cbb1fffa9cec54b7893e72f113fdba8f
