+Subject: s390x: Update math: redirect roundeven function
+
+After recent commit
+447954a206837b5f153869cfeeeab44631c3fac9
+"math: redirect roundeven function", building on
+s390x fails with:
+Error: symbol `__roundevenl' is already defined
+
+Similar to aarch64/riscv fix, this patch redirects target
+specific functions for s390x:
+commit 3213ed770cbc5821920d16caa93c85e92dd7b9f6
