Since the build machine and target machine is different, using -native configs doesn't work, and on this CPU, the application refuses to run due to the AES CPU flags being amiss. The patch passes EXTRA_CFLAGS to the figure-out-cpu-flags helper, which allows us to add -mno-aes to the compile flags and resolve this problem.
