[dpdk-dev] [PATCH 1/2] examples/ethtool: add to meson build

[Bruce Richardson]

Add the ethtool example to the meson build. This example is more
complicated than the previously added ones as it has files in two
subdirectories. An ethtool "wrapper lib" in one, used by the actual
example "ethtool app" in the other.

Rather than using recursive operation, like is done with the makefiles,
we instead can just special-case the building of the library from the
single .c file, and then use that as a dependency when building the app
proper.
