Linux x86_32 bits -- yes, they are effectively cross-compiled, so we first compile Linux x86_64 server (technically, my CI as well as GH actions reuse that binary from the dependent jobs), and then use it as build JDK during Linux x86_32 Zero compilation. `make bootcycle-images` is the go-to test to verify Zero works, as it uses the Zero binary as buildjdk on the second pass. The bootcycle times are bad, but not horrible after all the work I did over the last few weeks ;)
