cmd/compile: Go 1.22.x failed to be bootstrapped from 386 to ppc64le [1.22 backport] #67018
Description
@pmur requested issue #66955 to be considered for backport to the next 1.22 minor release.
@gopherbot please consider a backport to go 1.22. This prevents crosscompiling ppc64x code on 32 bit hosts.
