Hi,

this patch picks up Robin Dapps patch __tls_get_offset-in-separate.S.
See "Bugzilla 91628 - libdruntime uses glibc internal symbol on s390"
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91628)

The original purpose was to get rid of the usage of the glibc-internal 
symbol __tls_get_addr_internal.

The patch has not applied as is, therefore I've just regenerated the
configure and Makefiles.

Furthermore if build with multilib, the file
gcc/libphobos/libdruntime/config/systemz/get_tls_offset.S is used
for both configurations: systemz and s390.
Therefore both implementations are now in the systemz file which
uses an "#ifdef __s390x__" in order to distinguish both cases.
The s390 file is just including the systemz one.

Bye,
Stefan
