That's what I did: I found a 2017 stage3 with a still older glibc and 
managed to upgrade to a 2020 gentoo while masking the last glibc 
versions. That was tricky because I had to git-checkout intermediate 
versions of the portage tree in order to deal with the EAPI changes but 
I have a working chroot now. Thanks.
