patch 'build: pass cflags in subproject' has been queued to stable release 23.11.1

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/15/24. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=9796ac2ab87502888fc1a1d7252233d132b6ae41

Thanks.

Subject: [PATCH] build: pass cflags in subproject
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 3f9aa55632bd272981471516608a7eaf543bea37 ]

When DPDK is used as a subproject, include the required compile
arguments so that the parent project is also built with the appropriate
cflags (most importantly -march). Use the same cflags as pkg-config.

Fixes: f93a605f2d6e ("build: add definitions for use as Meson subproject")
