[dpdk-dev] [PATCH] dpaa: Augment linker line to include needed libraries for dpaa

[Neil Horman]

When preforming a shared library build, if the dpaa pmd is
configured, the build fails when linking testpmd.  This occurs because
the makefile fails to include dependent libraries dpaa_mempool and
dpaa_bus.

Fix is to simply include them in the makefile.  We could perhaps fix
this more generally by using the copy-dt-needed-entries linker option,
but doing so has a significant effect on link order, which may be
undesireable.  Given this is fairly isolated, and that we have precident
for this (see rte.app.mk), just add the needed libraries for this
specific app
