[dpdk-dev] [PATCH v2 1/2] ci: fix ABI reference generation

[David Marchand]

The machine=generic is not understood by older version of dpdk.
It is directly passed to gcc as -march=generic.

Since DPDK requires SSE 4.2, this results in an error when configuring
v21.02 sources for generating the reference ABI.

Stick to a compatible configuration passing -Dmachine=default.

Note: the breakage was not seen earlier this week as I guess the CI
workers are using a cached ABI reference for v20.11.

Fixes: 5b3a6ca6fd28 ("build: alias default build as generic")
