Subject: build: remove lto flags in dpdk build
X-Git-Tag: v23.02-rc0~42
X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=738eaa6f4965956a592392834bd1b6fcd0a20633;p=vpp.git

build: remove lto flags in dpdk build

- Ubuntu 22.04 enables LTO by default and dpdk
  adds lto flags to CFLAGS. This CI jobs to fail
  with OOM-Kill (especially on ARM64) due to lto
  consuming large amounts of memory.

Type: make
