Sure,

the link args for the helloworld example from build.ninja are now (snipping
out some .a's from the middle for brevity):

 LINK_ARGS = -Wl,--as-needed -Wl,--no-undefined -Wl,-O1 -Wl,--whole-archive
-Wl,--start-group lib/librte_telemetry.a lib/librte_bpf.a

The before case is below (again snipping some drivers):

/usr/lib/x86_64-linux-gnu/libisal.so -Wl,--end-group
'-Wl,-rpath,$$ORIGIN/../lib' -Wl,-rpath-link,/home/bruce/dpdk.org/build/lib

These both come from builds with meson 0.54. I can also check that things
look the same for 0.47 too.
