<pre>LLD seems to drop function pointers in the `.ctors` section that are not C++
constructors.
Example:
<a href="https://compiler-explorer.com/z/9dcG7c">https://compiler-explorer.com/z/9dcG7c</a>
There's a lot going on here with priority ordering, but the upshot that BFD LD
preserves function pointers (which are not C++ constructors) explicitly placed
into `.ctors` or `.ctors.*` with both GCC and Clang, but Clang+LLD drops them.
(The same happens with C, where there are no actual C++ constructors:
