That's true for glibc but it isn't entirely accurate to extend that to
"all userspace" since (AFAIK) none of the --with-cpu optimisations that
glibc does are ABI-changing.  So, it's just eglibc itself that needs to
get a different package architecture, everything else can stay with the
generic value.
