The syslinux-xcat subpackage is BuildArch: noarch but deliberately bundles the
arch-dependent PXELINUX/SYSLINUX bootloader blobs under
/opt/xcat/share/xcat/netboot/syslinux. EL10 rpm does not flag these real-mode
binaries, but EL8/EL9 rpm aborts the build with "Arch dependent binaries in
noarch package", so syslinux-xcat 6.03 could not be rebuilt for rh8/rh9 and the
2.17 -> 2.18 upgrade had no syslinux-xcat >= 6.03-1 to satisfy xCAT 2.18.
Set %_binaries_in_noarch_packages_terminate_build 0 so the self-contained xcat
netboot payload builds across EL8/EL9/EL10.
