patch 'config/arm: fix 32-bit build' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/02/26. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/39498ee79f240471e870792b975142d8e1037a37

Thanks.

Kevin

Subject: [PATCH] config/arm: fix 32-bit build

[ upstream commit a24b7345eb9375cb89d96ab08685a1511f1aa3e7 ]

When building for 32-bit arm with GCC versions >=11 and using the
DPDK-provided cross-file, the initial configuration step fails  The
error given is:

  config/meson.build:189:8: ERROR: Problem encountered: \
		Compiler does not support "armv8-a" arch flag.

but the real problem is actually an fpu-related error which is explained
in the meson log file:

  cc1: error: '-mfloat-abi=hard': selected architecture lacks an FPU

This error can be fixed by specifying an fpu explicitly, and a number of
options will work, e.g. -mfpu=neon, -mfpu=fp-armv8. Choosing the latter
here to avoid mandating neon by default.

Fixes: e754875c296c ("config/arm: add aarch32 cross-compilation")
