[dpdk-stable] patch 'build: fix meson binutils workaround' has been queued to LTS release 18.11.2

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/13/19. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/1ea1fb6f7e978b39aa615f0d0d8d2ae1d227f6bd

Thanks.

Kevin Traynor

Subject: [PATCH] build: fix meson binutils workaround

[ upstream commit 6e625189f25ca56859715b07732491f829619ec1 ]

The '-mno-avx512f' compiler flag is not passed to the compiler,
detection of the binutils and setting flags works fine, but the flag
itself not used by compiler.

Removing the interim 'march_opt' variable and using directly
'machine_args' and setting '-mno-avx512f' to 'machine_args'

Fixes: 566b4d7a968f ("build: fix meson check for binutils 2.30")
