Hi! Welcome to OpenJDK! I believe clang being forced to use lld is by design, in https://github.com/openjdk/jdk/pull/19456 this was done to make handling of command lines easier in the build system. Changing this to be flexible is probably still possible, but will involve some more work than just removing -fuse-ld=lld. Additionally, the OpenJDK build system does not typically use special variables that configure picks up- A configure option is encouraged instead
Thanks for coming to OpenJDK, and I hope you enjoy your stay here! :) best regards, Julian
