This header uses __set_errno(), so make sure we include errno.h for it.
Otherwise, if INLINE_SYSCALL() is used and errno.h isn't included, we
hit warnings like so:
In file included from libc-start.c:36:0:
../sysdeps/unix/sysv/linux/dl-osinfo.h: In function '_dl_setup_stack_chk_guard':
../sysdeps/unix/sysv/linux/dl-osinfo.h:79:7: warning: implicit declaration of function '__set_errno'
Which culminate in errors like so:
libc-start.c:(.text+0x692): undefined reference to '__set_errno'
libc-start.c:(.text+0x752): undefined reference to '__set_errno'
collect2: ld returned 1 exit status

how to account for the padding introduced by the .align directive).
