This is a continuation of #1040062, with two parts:
First, I would appreciate if an x32 porter could take a look
and approve that pie-{compile,link}.spec should also be dropped
on x32.
Changing gcc to default to PIE on x32 would likely work,
but the current situation with x32 being the only half-PIE
architecture due to the random set of packages with
hardening=+all being PIE and others not causes breakage.
