I don't think that GCC is always the best example to follow.
Nevertheless, wouldn't it be worth of phasing out the /lib64? I don't
know what is the history behind, but I don't think this layout is
conceptual.
I would like to have a layout similar to what Debian is doing, so that
shared libraries would go in /usr/lib/x86_64-redhat-linux/ and
/usr/lib64 would be a legacy symlink pointing to it.
Likewise.
That kind of layout would make it much easier to do cross compilation
because you could just take the whole /usr/lib/another-host-triplet/
directory from another architecture without it interfering with the host
libraries and use it for cross compilation purposes.
Yes, that /lib/<target> arrangement allows for all manner of things that
just aren't possible with /lib64.
https://wiki.debian.org/Multiarch/TheCaseForMultiarch is a good read.
It would be a lot of work transitioning to a new layout though.
That it is.
I'd rather move toward sysroot multiarch instead, which would expand
that benefit beyond libraries to basically everything.
But to do anything, RPM's handling of architectures needs to change.
Years ago, I had attempted to fix some of this upstream, but it didn't
make it in.
https://github.com/rpm-software-management/rpm/pull/1038
It didn't go in, but not because we disagreed with the concept as such.
Note that support for multi-arch in rpm is now on the roadmap for 4.20
