LLD does not support EM_S390. I don't know anyone is working on it (or
is interested at the support).

There may be a build system bug.
In GNU ld, -f --auxillary is an option. -fPIC is not:
% ld.bfd -fPIC -shared a.o
% readelf -d a.out | grep PIC
0x000000007ffffffd (AUXILIARY) Auxiliary library: [PIC]

Ah right, Nathan confirmed no LLD support for s390. Philip, we may
need to not use LD=ld.lld for s390. Not sure about the second error
message.

Got it, we will remove the usage of ld.lld for s390.
