I wish we knew what tools are out there parsing this line :-) The issue got reported by QA as 'inconsistency'. As the format of this string was never promissed to be an ABI I think we can go the other way around: change x86 to match ARM. Some scripts may need fixing but IMO this is acceptable. Let's just promiss to not change it in the future :-) -- Vitaly
