There is a known upstream llvm bug where clang>17 using libstdc++12 will result in many deprecated function warnings in relation to stable_sort. For rocm7.0 builds, we use clang20, and default libstdc++11, but another package for rocm7.0 installs stdc++12, which then causes all future uses of clang to use that version.
The request here is to get rid of or suppress the warning.
