[dpdk-dev] [PATCH] doc: add index file to doxygen dependencies

[Bruce Richardson]

The doxygen index file is not printed as a processed file by doxygen so it
does not appear in the output .d (dependency file) list automatically
generated. Therefore, for correct rebuild tracking, we need to explicitly
include it as a dependency of the doxygen job.
