[dpdk-dev] [PATCH 19.08 4/6] devtools/test-meson-builds: add testing of pkg-config file

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

The pkg-config file generated as part of the build of DPDK should allow
applications to be built with an installed DPDK. We can test this as
part of the build by doing an install of DPDK to a temporary directory
within the build folder, and by then compiling up a few sample apps
using make working off that directory.
