With this solution, you need to list all targets you want to compile.

An alternative could be to disable a target in the config file
based on the variable DPDK_TARGET set by load_env.
One hack, which does not need any change in the script I think,
is to set targetcc=disabled.
Or we could check a well defined variable after calling load-devel-config.
