[PATCH] test: Disable strict-aliasing warnings

[Pablo de Lara <pablo.de.lara.guarch-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

DPDK does not build on gcc 4.4, as it complains due to
strict-aliasing rules in virtual_pmd and link_bonding_mode4 tests,
with no errors in next gcc versions:

CC virtual_pmd.o
CC test_link_bonding_mode4.o
cc1: warnings being treated as errors
/root/dpdk/app/test/test_link_bonding_mode4.c: In function ‘test_mode4_expired’:
/root/dpdk/x86_64-native-linuxapp-gcc/include/rte_ring.h:645: error: dereferencing pointer ‘pkt.409’ does break strict-aliasing rules
/root/dpdk/x86_64-native-linuxapp-gcc/include/rte_ring.h:729: error: dereferencing pointer ‘pkt.409’ does break strict-aliasing rules
...
cc1: warnings being treated as errors
/root/dpdk/app/test/virtual_pmd.c: In function ‘virtual_ethdev_stats_reset’:
/root/dpdk/x86_64-native-linuxapp-gcc/include/rte_ring.h:645: error: dereferencing pointer ‘pkt.338’ does break strict-aliasing rules
/root/dpdk/x86_64-native-linuxapp-gcc/include/rte_ring.h:729: error: dereferencing pointer ‘pkt.338’ does break strict-aliasing rules

This patch fixes the compilation by disabling
these warnings.
