Fixed with gcc commit "S/390: Fix PR91628"
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=88e508f9f112acd07d0c49c53589160db8c85fcd

If somebody is backporting this fix, please also backport
gcc commit "S/390: Fix layout of struct sigaction_t"
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=434fe1a4092e12e5b518ef0716dc5b315e06118d

Otherwise you'll still see tls testsuite FAILs.
