This essentially reverts b841e119d7.
Such code construct can be used in the following way:
// glibc/stdlib/exit.c
// clang -fuse-ld=lld => succeeded
// clang -fuse-ld=lld -fpie -pie => relocation R_PLT_PC cannot refer to absolute symbol
__attribute__((weak, visibility("hidden"))) extern void __call_tls_dtors();
void __run_exit_handlers() {
if (__call_tls_dtors)
__call_tls_dtors();
}
Since we allow R_PLT_PC in -no-pie mode, it makes sense to allow it in
-pie mode as well.
