I remember reading a report here that someone ran into a link issue with PIE on x86 at build time (check went okay) and was able to resolve it via --disable-pie. Unfortunately I couldn't locate the post - do you remember what that was about? Was that some BSD rather than Linux maybe? It's probably a good idea to still allow overriding it, whether we white- or blacklist or trust a compile test.
