Bug 22173 – Target functions called through PLT in thunks

Inside _THUNKs, DMD calls functions through PLT. --- sub $0x8,%eax jmp 0xf7f06970 <_D5mydll1C3fooMFCQp1IZCQvQr@plt> --- This is bad because it means the GOT needs to be loaded inside EBX before the JMP, else a segfault occurs (see issue 9729, and issue 22170). GDC instead calls the aliased symbol directly: --- subl $0x8,0x4(%esp) jmp 0xf7f34ffb <_D5mydll1C3fooMFCQp1IZCQvQr> --- DMD 32-bit PIC should be more like GDC 32-bit PIC to avoid this trap.
