[PATCH] [dlang/phobos] S/390: Fix PR91628

[Robin Dapp]

Hi,

in order to not use a glibc-internal symbol anymore, this patch adds
separate .S files for s390x and s390 that allow to obtain the tls offset.

I bootstrapped on s390x -m64 and -m31 and test on s390x, s390 seeing no
new regressions.

Regards
 Robin
