This failure was probably due to a previous wrong configuration.
After "make clean", it works.

When looking at your wiki, there are more options used:
https://github.com/MarvellEmbeddedProcessors/dpdk-marvell/wiki/Building-and-Running
   --enable-bpool-cookie=64 \
   --enable-bpool-dma=64 \
   --enable-dma-addr=64 \
   --enable-sam

Are they needed?
