Subject: [PATCH] ads2gas: remove RN stanza

The matching on ads2gas_apple.pl is too liberal and catches
CONFIG_EXTERNAL_BUILD and CONFIG_INTERNAL_STATS because they have RN in
the names.

The RN renaming feature is not used in any existing assembly files. It
was used in some armv6 files but they were removed.
