I think this code in test-meson-build.sh should probably be fixed:
if [ ! -d $abirefdir/src ]; then
git clone --local --no-hardlinks \
--single-branch \
-b $DPDK_ABI_REF_VERSION \
$srcdir $abirefdir/src
fi
Like you noted, using -b allows us to checkout a tag/branch in the cloned
repository but requires that it exist locally. We should probably prefix the
checkout with a git fetch --tags
