[Bug c/45106] casting of variadic function pointers to normal function pointers causes segfaults on 64bit systems

[jakub at gcc dot gnu dot org]

Don't do it, it is not valid.
The x86-64 ABI requires that for varargs the %al register contains number of
SSE regs that need saving, while for non-varargs functions that register is
undefined.
