Thanks for opening this issue.

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)
There are several ways that the symbol will be considered non-preemptible:
* -pie
* -Bsymbolic
* STV_HIDDEN/STV_INTERNAL/STV_PROTECTED
* --dynamic-list exists but does not list the symbol
* VER_NDX_LOCAL
