[dpdk-dev] [RFC PATCH 3/3] build: write messages to dpdk build log file

[Bruce Richardson <bruce.richardson@intel.com>]

Add additional info into the DPDK-specific logs by copying or replacing all
"message()" calls with writes to the log file, making the build
configuration, including lists of enabled/disabled drivers etc. available
after the meson run has completed.
