I think this would be coming for parallel builds. Serial build for 
shared library is working as far as I know.
For parallel, somehow the rte_pmd_dpaa2_qbman dependency for net/dpaa2 
is not getting clearly defined because of which net/dpaa2 linking is 
attempted even before rte_pmd_dpaa2_qbman is ready.

I found that this might be because of the way scripts/depdirs-rule.sh 
forms the common-est directory. It works fine when dependent libraries 
are within lib/*, but when a drivers/net is dependent on driver/common 
or driver/bus, it somehow isn't working.

I am still investigating this.
