* ext/socket/extconf.rb: Implement
--{enable,disable}-close-fds-by-recvmsg-with-peek configure option for cross-compiling. Make --{enable,disable}-wide-getaddrinfo configure option cross-compiling friendly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40464 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
