Makefile: bugfix for parallel builds

When using "make -j" we must make silentoldconfig before building any object. Otherwise we may use the previous autoconf.h, in error if we just changed the configuration. This was exposed by ./MAKEALL with the properly working wr/non-wr build for wrs: previous wrcp_defconfig left CONFIG_EXT_WR active while building some file with wrs-nonwr_defconfig.
