Removing the PLT (same as PIE
https://github.com/dlang/dmd/blob/master/src/dmd/backend/elfobj.d#L3125), DMD
only ever seems to generate a jmp to an offset of the target function.

sub    $0x8,%eax
jmp    0xf7f06970 <_D5mydll1C3fooMFCQp1IZCQvQr+4>

Which also looks wrong in comparison to GDC and triggers a segfault.
