--- Comment #6 from Fangrui Song <i at maskray dot me> ---
> It is incorrect to reference a non-preemptible symbol with a PC relative relocation in a -pie link. GNU ld allows it but the code can be incorrect at runtime.

Correction: It is incorrect to reference a non-preemptible SHN_ABS symbol with
a PC relative relocation in a PIC (-shared or -pie) link. This is
non-representable due to ASLR (load base not fixed at link time)
