[dpdk-dev] [PATCH] ci: build and use libabigail 1.6

[David Marchand]

libabigail 1.2 (at least) reports changes in 'const' property as an ABI
breakage [1].
This was fixed upstream in libabigail 1.4 [2], and a bug has been opened
in launchpad [3].

But for now, build and use the last version 1.6 so that the ABI checks
can be kept.
