lvm/utils/release/test-release.sh parallel compilation parameter "-j" is not applied to all modules

[songdongsheng]

On a 16-core machine, although the parameter "-j3" is used, there are mostly 3 compilation processes during execution, but no less than 10 compilation processes can still be seen running.

cd /opt/llvm-build/llvm-18.x &&
    /usr/bin/time -v ./llvm/utils/release/test-release.sh \
        -release 18.1.0 \
        -rc 2 \
        -triple x86_64-unknown-linux-gnu \
        -j 3 \
        -use-ninja \
        -no-checkout \
        -no-compare-files

My guess is that this is the same as #80999.
