Try build a dynamic library, a lot function symbol and global

It can be done by pass `-Wl,-undefined,dynamic_lookup` or

Thanks your all for the tips, void solution fix me problem.
I need my struct defined as `isZeroInit`, so can I can import
them as `di` file. (this also reduce build size)
But I find this problem with float inside union:
```d
struct test_t {
union {
int i32;
float f32;
}
}
static assert(__traits(isZeroInit, test_t) );
