We're now seeing this instead when building the ptest part on poky-lsb
(which turns on more security flags):

raid6check.c: In function 'check_stripes':
raid6check.c:352:2: error: ignoring return value of 'posix_memalign',
declared with attribute warn_unused_result [-Werror=unused-result]
  posix_memalign((void**)&stripe_buf, 4096, raid_disks * chunk_size);
