Subject: s390x: Update math: redirect roundeven function
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fheads%2Fusers%2Fskpgkp2%2F2.33%2Fmaster;p=thirdparty%2Fglibc.git

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
"Update math: redirect roundeven function"

(cherry picked from commit 259a17cc98058d2576511201f85d28cb5d9de2a2)
