Problem with rebuilding golang-github-prometheus-alertmanager on FC38, FC39

Using toolbox with FC39 to demonstrate:

wget https://dl.fedoraproject.org/pub/fedora/linux/releases/39/Everything/source/tree/Packages/g/golang-github-prometheus-alertmanager-0.23.0-15.fc39.src.rpm 

toolbox create bug-prometeus-fc39 --distro fedora --release 39 -y 
toolbox -c bug-prometeus-fc39  run sudo dnf builddep -y ./golang-github-prometheus-alertmanager-0.23.0-15.fc39.src.rpm

toolbox -c bug-prometeus-fc39  run  sudo dnf install -y rpm-build

toolbox -c bug-prometeus-fc39  run  rpmbuild --rebuild ./golang-github-prometheus-alertmanager-0.23.0-15.fc39.src.rpm

We got

Same problem with FC38 (checked), and probably with Rawhide
