The new option processing machinery relies on %< rules in the specs to suppress options that are rewritten. Suppression appears to be a two phase process where the option is partially suppressed when %< is processed and then fully suppressed at the end of the string. Strings are separated by commas and there can be multiple strings used to form DRIVER_SELF_SPECS. The fix in this case is to separate the driver self specs for ARM into separate rules as described; this forces the -m{cpu,tune,arch}=native options to be properly removed before proceeding to the next rule set.
