I remember similar complaints back in the days when Fedora moved away from MD5
to SHA256, which broke RPMs which was built on RHEL-6 or newer Fedoras and was
attempted installed on RHEL-5. It didn't take too long before rpmbuild-md5
was discovered which resolved this issue.
Don't you think a similar utility will appear, or a RPM macro can be defined
to use the older compression? I don't know about anything right now, but this
cross building will be crucial for quite some users so I kinda expect this to
be a known issue.
