This assertion is not true. Because the DPDK doesn't work if you don't specify
the whole-archive link option. Which explicitly prevents stripping out any
"unused code". Otherwise your PMD's will refuse to initialize.
This along with backward compatibility is why I was advising to build the full
static library and the sublibraries so it will just work for everybody by
default.
Matthew.
