This seems to be triggered by the newer dpkg, which apparently emits
-pie itself on hurd-i386: on my not-so-up-to-date box I hadn't the
issue, and after upgrading dpkg&dpkg-dev I got the issue on my box too.

dpkg maintainers: ghc does emi -no-pie, but it seems dpkg's -pie
overrides it.

I'm however surprised that dpkg adds -pie on hurd-i386 too: AIUI hurd's
gcc does have pie enabled by default too.
