-Subject: [PATCH 1/2] build: avoid non supported -march on ppc (meson)
-
-So far only if machine was "native" it did use the re-direction to
-not set -march on ppc64 (where -march is not supported).
-We have to use mcpu/mtune in any case on ppc for whatever someone using
-the build system defines as machine.
-
-Fixes: 54d609a13876 ("build: add ppc64 meson build")

-Subject: [PATCH 2/2] build: establish an invariant machine type
-
-Add the machine definition 'default' which is special compared
-to 'native' (most optimized for current system) or any explicit
-type (external entity has to decide on the type).
-
-It defaults to the per arch agreed common minimal baseline
-needed for DPDK to reasonable work.
-
-That might not be the most optimized, but the most portable
-version while still being able to support the CPU features
-required for DPDK.
-
-Going forward this can be bumped up by the DPDK project, but it
-can never be an invariant like 'native'.
-
-Distributions and other needing portable code are expected to
-define the machine as 'default'.

-Description: build: set -mfpu=neon flag for armv7a builds
- Building on armv7a with meson currenctly fails:
-
- /usr/lib/gcc/arm-linux-gnueabihf/8/include/arm_neon.h:10369:1: error:
- inlining failed in call to always_inline ‘vld1q_s32’: target
- specific option mismatch
-
- Set -mfpu=neon on that architecture like the legacy makefiles do to fix
- the issue.
