I was curious and checked if the problem was gone on v2.1.0, but it still happens there.

Comment 9 cJ 2022-04-01 13:16:26 UTC

It's the multilib x86 portion of the build that fails due to presence of the 64-bit libunwind ; USE="-abi_x86_32" builds.

Comment 10 cJ 2022-04-01 13:42:51 UTC

The unwind issue is brought indirectly by glog, whose glog-config.cmake simply does:
find_dependency (Unwind 1.6.2)
and uses its own FindUnwind which was broken until
https://github.com/google/glog/pull/769/files#diff-d4308e6c6735dd82d755ac06d881951f963438a1929f6fca82a5593d8b15083bR55
(not tagged yet).

I suggest to include a glog patch?
