Sorry, scratch that, I forgot the `extern` before the dummy
global. After fixing that, I didn't quickly find a solution for
referencing the symbol in the .data.rel.ro section (LLVM asm,
e.g., `void* getInit() { return __asm!(void*)("movq
test.C.__init, %rax", "={rax}"); }` doesn't work either).
The compiler could emit the init symbol as regular global for
`-betterC` though.

This issue could also be tackled in the D ctor of the extern(C++)
class, by injecting the blit before the actual ctor body. C++
code wouldn't have to take care about that D-interop
incompatibility anymore (independent of -betterC).
