Makerules: fix MAKEFLAGS assignment for upcoming make-4.4 [BZ# 29564]
make-4.4 will add long flags to MAKEFLAGS variable: * WARNING: Backward-incompatibility! Previously only simple (one-letter) options were added to the MAKEFLAGS variable that was visible while parsing makefiles. Now, all options are available in MAKEFLAGS. This causes locale builds to fail when long options are used: $ make --shuffle ... make -C localedata install-locales make: invalid shuffle mode: '1662724426r' The change fixes it by passing eash option via whitespace and dashes. That way option is appended to both single-word form and whitespace separated form. While at it fixed --silent mode detection in $(MAKEFLAGS) by filtering out --long-options. Otherwise options like --shuffle flag enable silent mode unintentionally. $(silent-make) variable consolidates the checks.
