[dpdk-dev] [PATCH 2/2] mk: fix two more missing libm dependencies

[Panu Matilainen <pmatilai@redhat.com>]

Commit e86a699cf6b1 missed two further libm dependencies: ceil() used by
librte_meter is typically inlined so the missing dependency does not
actually cause failures, and librte_pmd_nfp is not built by default
so its easy to miss.

This causes duplicates in LDLIBS in many configurations so its vital
they are removed before passing to linker.

Fixes: e86a699cf6b1 ("mk: fix shared library dependencies on libm and librt")
