mk: install a standard cutomizable tree The rule "install" follows these conventions: http://gnu.org/prep/standards/html_node/Directory-Variables.html http://gnu.org/prep/standards/html_node/DESTDIR.html The variable sdkdir has been added to the more standards ones, to configure the directory used with RTE_SDK when using the DPDK makefiles to build an application. It is still possible to build DPDK with the "install T=" rule without specifying any DESTDIR. In such case there is no install, as before. The old usage of an installed SDK is: make -C examples/helloworld RTE_SDK=$(readlink -m $DESTDIR) \ RTE_TARGET=x86_64-native-linuxapp-gcc RTE_TARGET can be specified but is useless now with an installed SDK. The RTE_SDK directory must now point to a different path depending of the installation.
