Nak, for a few reasons:

1) While this target is in a common makefile, at least some of the information
it gathers is operating system specfic (e.g. /proc/meminfo).  This isn't going
to work on BSD, or other operating systems that we might support in the future

2) This is tied to the build system.  Theres no guarantee that users will
diagnose problems only on the system that they built the DPDK on.  

A better solution might be to simply document the sort of information that a bug
reporter is expected to gather, along with some sample tools for doing so.
There are numerous tools to get the above information, both in isolation and in
aggregate.
