[PATCH v3 14/14] Fix the compiling of test-pmd on IBM Power Architecture

[Chao Zhu <chaozhu-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>]

This patch fixes compiling problems on IBM Power architecture and turn
on the test-pmd compiling option in configuration file. Actually, this
is an big endian compiling fix.
