I had a suspicion that this issue is similar to https://bugs.gentoo.org/837746 in that the interpreter is set incorrectly for provided ELF files. Following https://bugs.gentoo.org/682370 and adjusting the interpreter of the ELF files under ${WORKDIR}/rust-stage0/bin I'm able to build rust-1.62.1. A minimal patch is attached.
Created attachment 799835 [details, diff] interpreter patch
Just yesterday I ran into the same issue and I can confirm that the patch in comment 5 works for me for rust version 1.66.1.
