How compatible are we looking for here. The standard way of compiling up DPDK
up till now has always been "make install T=$RTE_TARGET", but that seems to no
longer work.

bruce@silpixa00389037-Fedora:dpdk-clean$ echo $RTE_TARGET
x86_64-native-linuxapp-gcc

bruce@silpixa00389037-Fedora:dpdk-clean$ make install T=$RTE_TARGET
/home/bruce/dpdk-clean/mk/rte.vars.mk:58: /home/bruce/dpdk-clean/build/.config: No such file or directory
/home/bruce/dpdk-clean/mk/rte.vars.mk:83: *** RTE_ARCH is not defined.  Stop.
/home/bruce/dpdk-clean/mk/rte.sdkroot.mk:98: recipe for target 'install' failed
make: *** [install] Error 2

When I look for backward compatibilty, this is the main thing I look for, as I'm
not aware of anyone (on my team here at least!) who does a make config first etc. 
When developing, most people just do a "make install T=..."straight up.
