It's always equal ARCH and not very useful (so nothing actually uses it). Time for a change: SUBARCH now is meaningful and gives a way to detect what kind of ARCH flavor build is dealing with. Also, for cross-compiling sake don't set SUBARCH if the user supplied it. (and don't call useless uname during cross compilation) Signed-off-by: Dmitry Safonov <dima@arista.com> Signed-off-by: Andrei Vagin <avagin@gmail.com>
