Suse11 SP3 default gcc version is 4.3.4, some options not support on this version.

error: implicit declaration of function ‘_mm_alignr_epi8’
solution: include tmmintrin.h when enable SSE3

error: unrecognized command line option "-Wno-unused-but-set-variable"
solution: add version check in fm10k Makefile

error: enic_main.c:845: error: initialized field overwritten
solution: change struct initialization code

error: ‘testfn_pci_cmd’ defined but not used
solution: add __attribute__((unused)) before function definition

error: unrecognized command line option "-fno-var-tracking-assignments"
solution: add version check in app/test/Makefile

error: implicit declaration of function ‘pread’
solution: add _GNU_SOURCE flag when compile eal_pci_uio and eal_interrupts
