How can I link my dmd-compiled program with a specific version

druntime is within libphobos. So you must change this.
I need this when experimenting with a new GC.
Did you try what i proposed earlier ? Until the handlers are
plugged there can be a fallback to the manual allocs.
For example you start with the manual implementation and add
handlers + fallback for every functions, like here for malloc
```
__gshared void* function(size_t, uint, const TypeInfo)
nothrow mallocHandler;
void* malloc(size_t size, uint bits, const TypeInfo ti)
nothrow
{
if (mallocHandler) // experimental stuff
{
return mallocHandler(size, bits, ti);
}
else // fallback until handler is assigned
{
void* p = cstdlib.malloc(size);
if (size && p is null)
onOutOfMemoryError();
return p;
}
}
```
this way you can very easily change-compile-test, without
recompiling the whole runtime and phobos each time.
