* scripts/abilist.awk: Produce a more compact format, divided into
stanzas for each version set, the set name listed only once. * scripts/extract-abilist.awk: New file. * scripts/merge-abilist.awk: New file. * Makerules (check-abi-%, update-abi-%): New pattern rules. (update-abi, check-abi): New targets. * Makefile (+subdir_targets): Add subdir_{check,update}-abi. * Makerules (%.symlist): Use LC_ALL=C when running awk script.
