libFuzzer is only an unstable package, so can't really block stabilization this failure is when building for a 32-bit target. upstream has rewritten this particular bit of code entirely, so we can hack it locally until the next release. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=20247e5bb4a1d133a17eac3f57ac56defe3f656c
