All I'm trying to do is build 32-bit JDK on 64-bit linux which has been 
working fine for ages until these recent glitches. :( I'm dependent on 
this working.

If something is being done incorrectly here let me know and I will fix 
it. We are just about the push the minimal VM changes and that will 
require a follow up to make build-infra recognize the minimal JVM_VARIANT.

ASFLAGS is used by the VM - significantly to pass the ARCHFLAG value ie -m32
