coreutils-testsuite too. - Don't call autoreconf on distributions older then 12.0 because their autoconf is too old. - Update default posix version to 200112 (bnc#783352). - Add coreutils-df-always-hide-rootfs.patch: Hide rootfs in df (df not using yet /proc/self/mountinfo). - Statically link to gmp otherwise expr depends on gmp and gmp configure script depends on expr which creates a build cycle. - Add the missing parts in coreutil.spec so that the testsuite is only run when coreutils-testsuite is built. Also add additional BuildRequires for the testsuite. - Hardcode the name passed to find_lang so that it works for coreutils-testsuite too. - Don't call autoreconf on distributions older then 12.0 because their autoconf is too old.
