Hi Francesco,

Actually, the current behavior of install target is to build one or
several targets from templates given in the T=. To be clear, this line:

  make install T=*-native-linuxapp-gcc

is equivalent to:

  make config T=i686-native-linuxapp-gcc O=i686-native-linuxapp-gcc
  make O=i686-native-linuxapp-gcc
  make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
  make O=x86_64-native-linuxapp-gcc
  make config T=x86_x32-native-linuxapp-gcc O=x86_x32-native-linuxapp-gcc
  make O=x86_x32-native-linuxapp-gcc

The target name "install" is probably not well chosen, and that's
probably why you are confused.

Mario is currently reworking the Makefiles to support the installation
of DPDK into a hierachical file system:
