[dpdk-dev] [RFC 6/6] build: add drivers abi checks to meson

[Kevin Laatz]

This patch adds the ABI compatibility check for the drivers directory to
the meson build. If enabled, the ABI compatibility checks will run for all
.so's in the lib directory (provided a matching dump file exists). The
build will fail if an ABI incompatibility is detected.
