The -fpic came from libiberty/configure.ac, with no explanation. Since
the PICFLAG setting is supposed to be generically usable, I'd suggest to
remove the -fpic setting in picflag.m4 instead. If you still prefer to
stay with that value, please change s390/t-crtstuff instead of the
shared t-crtstuff-pic, with a comment giving the rationale.
Thanks.
