[dpdk-dev] [PATCH 1/2] config: remove obsolete machine descriptions

[Thomas Monjalon <thomas.monjalon@6wind.com>]

More and more machines and architectures are added without keeping
the lists up-to-date.
Replace the lists with a pointer to the reference directory.
The same kind of pointer is used for the supported compilers and environments.
