[patch] gcc6 FreeBSD rs6000 PIE handling

[Andreas Tobler]

Hi,

this is the part for gcc trunk. As mentioned in the previous mail (same 
subject for gcc5) I forgot to adapt the PIE bits for FreeBSD powerpc64.

The patch below lets me bootstrap a current gcc with itself.

I'll commit this part if there are no objections.

Thanks,
Andreas
