_LDLIBS is an internal variable of rte.app.mk.
Please could you check that there is no issue when using LDLIBS instead
of _LDLIBS?

LDLIBS is not helping the situation as LDLIBS comes before the _LDLIBS-y
mk/rte.app.mk:LDLIBS += $(_LDLIBS-y) $(CPU_LDLIBS) $(EXTRA_LDLIBS)

But moving to EXTRA_LDLIBS looks OK.But it has to be under CONFIG_RTE_LIBRTE_IXGBE_PMD

Thomas, Ferruh
Let me know if you have any objection on below mentioned diff

-ifeq ($(CONFIG_RTE_BUILD_SHARED_LIB),y)
-_LDLIBS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += -lrte_pmd_ixgbe
+ifeq ($(CONFIG_RTE_LIBRTE_IXGBE_PMD),y)
+EXTRA_LDLIBS += -lrte_pmd_ixgbe
 endif

You need to keep the shared lib check.
Anyway, EXTRA_LDLIBS should be reserved to users and not used in a Makefile.
I prefer your initial patch using _LDLIBS.

Any objection to merge initial proposal?
