In lib/sys_random.in.h I used <stddef.h>, because
  - it's more "minimal" than <stdlib.h>: it defines fewer unrelated symbols,
  - it is less likely to cause problems with mutual inclusion of gnulib
    overridden header files.

I don't object to adding '#include <stddef.h>' in the two *.m4 files. It's
redundant, but it won't hurt either.
