ArchLinux now update glibc to 2.42+r2 at this version, uabs is `extern`. and in hotspot/src/share/vm/utilities/globalDefinitions.hpp file, uabs is also static, maybe we should check glibc version for this function

And, java11-openjdk, java17-openjdk, java21-openjdk, java-openjdk (jdk24) package have this error too.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
git clone https://gitlab.archlinux.org/archlinux/packaging/packages/java8-openjdk
cd java8-openjdk
makepkg -s

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
successfully build java{8,11,17,21,}-openjdk packages
ACTUAL -
receive compile error as above
