[dpdk-dev] [PATCH 03/10] mk: install a standard cutomizable tree

The rule "install" follows these conventions:
https://www.gnu.org/prep/standards/html_node/Directory-Variables.html
https://www.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.
The old installed tree was static and always had .config, includes and
libs in a RTE_TARGET subdirectory. There is no such directory anymore in
an installed SDK. So the top directory is checked.
But RTE_TARGET can still be used, especially to build an app with a
compiled but not installed SDK.
That's why both cases are looked for RTE_SDK_BIN.
The default prefix /usr/local is empty in the T= case which is
used only for a local install.
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.
