Updating casefold.h
* common.mk (lib/unicode_normalize/tables.rb): should not depend on Unicode data files unless ALWAYS_UPDATE_UNICODE=yes, to get rid of downloading Unicode data unnecessary. [ruby-dev:49681] * common.mk (enc/unicode/casefold.h): update Unicode files in a sub-make, not to let the header depend on the files always. * enc/unicode/case-folding.rb: if gperf is not usable, assume the existing file is OK. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55492 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
