The xrootd package runs tests during the build. Some of these tests use
some precompiled binaries that are donwloaded from google to run. This
download attempt happens on amd64, arm64 and x32 -- the software is
available for x86_64 and aarch64 only, but the processor match in the
cmake script also triggers on x32 since it checks processor type and
not build target. If the download fails the tests needing this software
are disabled and not run.

On amd64 and arm64 buildds this works as expected -- the downloads fail
because the network is not available and the tests are akipped:
