[dpdk-dev] [PATCH] rte_trace: fix build on PPC64

[Thinh Tran <thinhtr@linux.vnet.ibm.com>]

The AltiVec header file breaks boolean type:

In file included from ../lib/librte_mempool/rte_mempool_trace_fp.h:18:0,
                 from ../lib/librte_mempool/rte_mempool.h:54,
                 from ../lib/librte_mbuf/rte_mbuf.h:38,
                 from ../lib/librte_net/rte_ether.h:23,
                 from ../drivers/common/mlx5/mlx5_nl.h:10,
                 from ../drivers/common/mlx5/mlx5_nl.c:23:
../lib/librte_eal/include/rte_trace_point.h: In function
‘__rte_trace_point_fp_is_enabled’:
../lib/librte_eal/include/rte_trace_point.h:226:9: error: incompatible
types when returning type ‘int’ but ‘__vector __bool int {aka
__vector(4) __bool int}’ was expected
  return false;

This is the same as
 https://git.dpdk.org/dpdk/commit/?id=725f5dd

and yet, there is no better solution for it
