The EARLY_BUILD flag tightly coupled the bsd.*.mk files to the build system,
so I’l like to see it stay dead. 9.x assumes that by defining it, it can affect
the system installed .mk files in a specific way. This is an unwise assumption,
as this thread demonstrates.

The real problem, imho, is that the construct in bsd.prog.mk is generating a
dependency on the wrong C++ standard library. Why is it generating for the
g++ library when the compiler is clang? That seems like the real bug here.

I’ll also note that building release X-2 on head isn’t generally supported by
the project, but having said that, I’ll see what I can do. Surprisingly, I don’t
have a good -current environment setup on my fast build boxes, so I’ll
setup a quick jail and see if I can recreate.
