Comments below concern added feature with patch 2.

More problematic, linking an external (out of meson) application to a
dpdk compiled with ASan is broken.

My environment contains following targets compiled using
./devtools/test-meson-builds.sh:
$ ls $HOME/builds/
build-arm64-bluefield  build-arm64-host-clang  build-clang-shared
build-gcc-shared  build-ppc64le-power8  build-x86-mingw
build-arm64-dpaa       build-arm64-octeontx2   build-clang-static
build-gcc-static  build-x86-generic

I stopped at patch 1, configured following target to have ASan in
them, like this:

$ meson configure $HOME/builds/build-gcc-static -Db_sanitize=address
$ meson configure $HOME/builds/build-clang-shared -Db_sanitize=address
-Db_lundef=false
$ meson configure $HOME/builds/build-x86-generic -Db_sanitize=address
                               ^^^^^^^^^^^^^^^^^
                               This is the target for which we test
linking a dpdk application out of meson.

$ meson configure $HOME/builds/build-arm64-bluefield -Db_sanitize=address

Then ran the check:
$ ./devtools/test-meson-builds.sh

*flood of errors about undefined symbols from libasan*


Tried to debug, in-tree compiled testpmd shows:
$ readelf -d $HOME/builds/build-x86-generic/app/dpdk-testpmd | grep asan
 0x0000000000000001 (NEEDED)             Shared library: [libasan.so.6]
But I see nothing in ninja:
$ grep -i asan $HOME/builds/build-x86-generic/build.ninja

And for external link, looking at an "installed" .pc:
$ PKG_CONFIG_PATH=/home/dmarchan/builds/build-x86-generic/install/usr/local/lib/pkgconfig
pkg-config libdpdk --libs | grep asan

Same problem, below should be in patch 2, from here...

This comment should be in patch 2, there is nothing specific in patch
