Commit 3eca75de67 introduced the #error
nagging about use of -fPIE, but it makes the transition quite difficult
for people using other buildsystems. So let's give people a grace period
and enforce only for GCC >= 5.
Clang is affected, but differently. The problem only happens with -flto
-- that is, it happens when the linker detects that it's creating a
final executable. Maybe -Wl,-pie would fix it.
