[swift-corelibs-dev] Unresolved enumeration symbols

[Joseph Bell]

Information about the system I'm building with, will note it doesn't have
anything else "special" i.e., no 4.x kernel or non-standard libc.  It is
really interesting, everything compiles okay, no errors thrown, etc.  I'm
going to try a build on a 15.10 VM as well to see if I can reproduce.
