During app build with static library, some libraries wrapped with
--whole-archive compiler flag.

Wrapped libraries are mainly PMD libraries, this is required because PMD
APIs not directly called but run through callbacks registered via
constructor functions.

Also some set of libraries, depends to the PMD libraries needs this,
because of same reason.

All the libraries used by a plugin (any driver) must be in --whole-archive
to ensure that every symbols will be available for the plugin.
This should be explained in this patch (verbatim copy allowed).

But other libraries can be out of this flag, and this saves some size in
final binary.

[...]

+_LDLIBS-$(CONFIG_RTE_LIBRTE_TIMER)          += -lrte_timer
+_LDLIBS-$(CONFIG_RTE_LIBRTE_EFD)            += -lrte_efd
+_LDLIBS-$(CONFIG_RTE_LIBRTE_CFGFILE)        += -lrte_cfgfile
+
 _LDLIBS-y += --whole-archive

Yes we can move these libraries out of --whole-archive as they are not
used by any driver.
