target-i386: Make TCG feature filtering more readable
Instead of an #ifdef in the middle of the code, just set TCG_EXT2_FEATURES to a different value depending on TARGET_X86_64. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
