I tried building on ARM just for the heck of it, and ldc2 compiles
successfully, but when I compile druntime, odd things happen.
Specifically, looking at the version blocks in core/stdc/stdargs.d, I
should be getting a static assert failure because my platform is
unsupported, but instead I'm seeing this:

$ ldc2  core/stdc/stdarg.d

This is odd because stdarg contains no import statements. Is the
compiler generating references to the other modules somehow, and if
so, why do I get these errors instead of the unsupported platform
error?
