> Added new environment variable RTE_TEMPLATE which is an additional
> variable that can be set in the users environment. This maps on to the
> existing 'T' command line variable typically used when 'make config'
> or 'make install' is invoked.
> 
> So, instead of typing 'make config T=x86_64-native-linuxapp-gcc', the user
> can now do 'export RTE_TEMPLATE=x86_64-native-linuxapp-gcc' followed by
> 'make config'. If the user instead chooses to 'make install', this will
> do the configure, build, and install in one step.
