Building DPDK with gcc 11 (and later versions) on a ppc64le system with RHEL
8.7 produces a segmentation fault when running the acl_autotest:

$ meson build && meson test -C build --suite DPDK:fast-tests
...
[2397/2397] Linking target app/test/dpdk-test
 1/71 DPDK:fast-tests / acl_autotest                        FAIL            
1.27s   killed by signal 11 SIGSEGV

>>> /home/drc/src/dpdk/build/app/test/dpdk-test --no-huge -m 2048
>>> --file-prefix=acl_autotest

Building the same code with -O2 works correctly:

$ meson -Doptimization=2 build && meson test -C build --suite DPDK:fast-tests
